Do you love math? Or are numbers the of your existence? Whether you're a fan of math or not, it's an important subject to learn. Just think of all the things you couldn't do without basic math! Math helps you buy food at the grocery story. It even helps you cook and divide it among your family members. Face it, folks. We need math!

Most of us start our mathematical journey learning the basics of addition. From there, we move on to subtraction. After we've mastered the pluses and the minuses, we advance to multiplication and division. Sooner or later, we all reach the point where we make the leap into more advanced math. What are we talking about? Algebra, of course!

Some people refer to algebra as the point at which letters get involved in math. Algebra is the study of mathematical and the rules for manipulating those . It forms the basis for advanced studies in many , including mathematics, science, engineering , medicine, and .

In its simplest form, algebra involves using equations to find the unknown. Real-life problems probably drove the development of algebra. The subject dates back over 4,000 years to the ancient Babylonians.

Here's an example. A wagon carries a load of hay bales. Suddenly, it hits a rut in the road. Six bales fall off! Luckily, ten bales are left. How many bales of hay did the wagon have when before it hit the rut? You can use the algebraic expression "x - 6 = 10" to answer this question. In this , x represents the unknown (how many bales of hay were on the wagon at the start). Six is the number of hay bales that fell off, and ten is the numbers still on the wagon. By adding six to each side of the , you'll find that x equals 16. So, the wagon had 16 hay bales before it hit the rut in the road.

Algebra gets much more complicated than that simple . This leaves many students WONDERing when, if ever, they'll use algebra in real life. Does it have any use? If not, why do you have to learn it?

For starters, algebra is foundational for other classes. That means you'll apply what you learn in algebra throughout school. Learning algebra helps to develop your thinking skills. That includes problem solving, , patterns, and reasoning. You need to know algebra for many professions, especially those in science and math. Not planning to go into those ? You'll probably still use algebra without even realizing it!

Consider these examples: It's time to fill up your car's gas tank. The price of gas per gallon is $3 and you only have $25 to spend. How much gas can you purchase? This can be answered by the algebraic , "3x = 25." You must divide each side of the by 3 in order to isolate x. In this , x is equal to 25 divided by 3, which is 8.33 gallons of gas. If you need 10 gallons of gas, how much money do you need? When you solve that , you have algebra to thank!

Or how about this example? You would like to purchase Internet service for your home. Company A requires a setup fee of $10 and charges a monthly fee of $25. Company B does not charge a setup fee but charges $26 per month. Which company is less expensive for one year of service? We can find out by first calculating the total cost for Company A: x = $10 + $25*12 (months in a year), which comes to $310. The for Company B is x = $26*12, which totals $312. At first glance, it might have seemed like Company B would be cheaper, because they do not charge a setup fee, but algebra showed us differently!

There are many other examples of real-world uses of algebra, from comparing prices on similar products in a grocery store to figuring out what time you need to leave your house in order to meet a friend across town on time. If you ever WONDER why you need to learn something like algebra, don't be afraid to ask your teacher or parent (or Wonderopolis!). Odds are, there's a good reason!

Why do I have to learn fractions and decimals?
It's a common refrain in every classroom, among students of all ages. And the adult students working towards an HSE are no exception.

Of course, there's one BIG reason you need to learn fractions (or any other subject on the HSE test):

To complete the assignment, move up a level in math, take the practice tests, and then the real test. You need to know fractions to graduate and to begin the next chapter of your life.

But more importantly, and their counterpart, are used so much daily that we don't even realize when we are using them.

Here are 20 ways fractions will sneak into your daily life.

1. EATING OUT: Have you ever gone out to eat with a group of friends but the waitress brings only one check? To divide up the bill, you'll need to use fractions.

2. BACK TO SCHOOL SHOPPING: Your son really wants those new Lebron kicks and you've agreed to pay ½. How much are they if you find a ¼ off sale?

3. GROCERY SHOPPING: You set aside your grocery budget and made your list. Sales tax and coupons all use fractions.

4. MEAL PREP FOR THE FAMILY: Cooking for 4 people but the recipe serves 10? You'll need to use fractions to divide the ingredients.

5. SPORTS: The NBA Finals are on. Fractions are used to determine statistics and shooting percentages.

6. CONTRACT WORK: Buying a car? Signing a lease on an apartment? Making your own jewelry and working with a supplier? For all of these things (and many others) you'll need to use fractions when negotiating the contract rates.

7. FITNESS: Before starting a diet, you should know your Body Mass Index. This BMI number is calculated using fractions. Dieting? You'll need fractions to know how many calories you are taking in vs. how many calories you are using.

8. JEWELRY: 24 karats is pure gold, and 18 karats is 18/24 which equals 75% gold. Using fractions to understand jewelry purity could save you money!

9. COCKTAILS: Good bartenders know how to mix drinks and fractions are used to determine how much of each ingredient is added.

10. PIZZA FOR THE KIDS: Mealtime doesn't have to be a battle about who got more. Use fractions to split the pie evenly.

11. PAY: Did you recently get a raise? Does a quarter of your pay go towards healthcare? How much should you invest in retirement? Fractions will determine how much you actually take home.

12. MONEY IN GENERAL: A quarter is a ¼ of a dollar. Dimes are 1/10 of a dollar. If you know fractions, adding your money is quick and easy.

13. GAS TANK: If you've got an 1/8 of a tank, how much further can you drive? Prices to fill up also use fractions.

14. FAST FOOD: Can you eat two quarter-pounders with all of the toppings? You've just consumed a half a pound of meat.

15. PHOTOGRAPHY: Shutter speed is calculated using fractions of a second.

16. HOMEWORK ASSIGNMENTS: Your child got 38/51 questions correct. A solid understanding of fractions will help you determine if the child should be rewarded or grounded.

17. PRESCRIPTIONS: Whether you, your child, or your pet is sick, medicine dosages are often determined with a fraction of parts to weight. Different body sizes require different dosages.

18. PARTY PLANNING: Use fractions to determine how much food to get, how many drinks you'll need on hand, and table settings.

19. CHECKING PROGRESS: Use fractions to determine rate of improvement. For example, if you called 25% more customers this month than last month, you might want to ask for a raise.

20. TIME: An hour and a half. A quarter of an hour. Time is commonly measured in fractions.

What if Math Is a Fundamental Part of Nature, Not Something Humans Came Up With?

# data[].attributes.attachment_link.readable_text
Nature is an unstoppable force, and a beautiful one at that. Everywhere you look, the natural world is laced with stunning patterns that can be described with mathematics. From bees to blood vessels, ferns to fangs, math can explain how such beauty emerges.

Math is often described this way, as a language or a tool that humans created to describe the world around them, with precision.

But there's another school of thought which suggests math is actually what the world is made of; that nature follows the same simple rules, time and time again, because mathematics underpins the fundamental laws of the physical world.

This would mean math existed in nature long before humans invented it, according to philosopher Sam Baron of the Australian Catholic University.

"If mathematics explains so many things we see around us, then it is unlikely that mathematics is something we've created," Baron writes.

Instead, if we think of math as an essential component of nature that gives structure to the physical world, as Baron and others suggest, it might prompt us to reconsider our place in it rather than reveling in our own creativity.

A world made of math

This thinking dates back to Greek philosopher Pythagoras (around 575-475 BCE), who was the first to identify mathematics as one of two languages that can explain the architecture of nature; the other being music. He thought all things were made of numbers; that the Universe was 'made' of mathematics, as Baron puts it.

More than two millennia later, scientists are still going to great lengths to uncover where and how mathematical patterns emerge in nature, to answer some big questions - like why cauliflowers look oddly perfect.

"We spent many hours frantically dismantling [cauliflower] florets, counting them, measuring angles between them," writes University of Nottingham mathematician Etienne Farcot, who studied cauliflower growth in an effort to understand these "mysterious cabbages."

Fractals are exquisite, self-repeating patterns which, besides some cauliflowers, are also found in fern fronds, branching blood vessels, and the rings of Saturn. Fractals are geometrical shapes made up of smaller and smaller copies of themselves, creating a mesmerizing 'self-similarity' that is infinitely deep.

Although only mathematical or computer-generated fractals are truly perfect fractals, nature comes pretty close.

"These repeating patterns are everywhere in nature," says mathematician Thomas Britz of the University of New South Wales in Sydney, Australia. "In snowflakes, river networks, flowers, trees, lightning strikes - even in our blood vessels."

Part of the charm of fractals is that they help to explain how complexity is born out of simplicity. As Benoît Mandelbröt, the Polish-born mathematician who coined the term fractal, said in 2010: "Bottomless wonders spring from simple rules which are repeated without end."

Branching river systems also carve near-perfect fractal patterns in the landscape.

So persistent are these patterns that in one instance, archaeologists looked for missing fractals to deduce ancient Egyptians might have modified river channels when building pyramids nearby.

Insects appear to follow mathematical principles, too.

Whether they know it or not, bees build hexagonal honeycomb in a way that produces the most storage space using the least materials - a theory known as the 'honeycomb conjecture' which was finally demonstrated by American mathematician Thomas Hales in 1999.

Some species of cicadas also have a life cycle geared towards prime numbers. Swarms of two North American species emerge from their subterranean burrows every 13 or 17 years, a trick which scientists think helps cicadas avoid predators with more regular rhythms.

Let's not forget nature's 'favorite' numbers, Fibonacci numbers, where each number in the sequence is the sum of the previous two. Fibonacci numbers are seen in sunflower seeds, pine cones and pineapples.

Spiral galaxies and nautilus shells also mimic so-called golden spirals by growing in a logarithmic ratio with every quarter turn.

But even though mathematical patterns are everywhere to be seen in nature, recent discoveries suggest the connection between math and nature runs deeper still, in ways we're only just beginning to appreciate.

Earlier this year, researchers discovered what they described as a previously unknown law of nature: a growth pattern which describes how pointed shapes form again and again in nature - from shark teeth and spider fangs to bird beaks and dinosaur horns.

"The diversity of animals, and even plants, that follow this rule is staggering," evolutionary biologist Alistair Evans from Monash University in Australia said at the time they discovered the mathematical formula, dubbed the 'power cascade'.

"We found it almost everywhere we looked across the kingdoms of life - in living animals, and those extinct for millions of years."

Back in 2015, scientists were also delighted to find a classic formula for Pi - the ever-constant ratio between a circle's circumference and its diameter - lurking in hydrogen atoms.

In a roundabout way, that discovery leads us back to the idea that mathematics provides a structural framework for the physical world. It's an interesting idea to entertain - so long as your head doesn't explode.

Sometimes we need to solve Inequalities like these:

Solving

Our aim is to have x (or whatever the variable is) on its own on the left of the inequality sign:

We call that "solved".

Example: x + 2 > 12

Subtract 2 from both sides:

x + 2 − 2 > 12 − 2

Simplify:

x > 10
Solved!
How to Solve

Solving inequalities is very like solving equations, we do most of the same things ...

... but we must also pay attention to the direction of the inequality.

Direction: Which way the arrow "points"

Some things can change the direction!

Safe Things To Do

These things do not affect the direction of the inequality:

Add (or subtract) a number from both sides

Multiply (or divide) both sides by a positive number

Simplify a side

Example: 3x < 7+3

We can simplify 7+3 without affecting the inequality:

3x < 10

But these things do change the direction of the inequality ("<" becomes ">" for example):

Here are the details:

Adding or Subtracting a Value

We can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra), like this:

Example: x + 3 < 7

If we subtract 3 from both sides, we get:

x < 4

And that is our solution: x < 4

In other words, x can be any value less than 4.

What did we do?

We went from this:

To this:

x+3 < 7

x < 4

And that works well for adding and subtracting, because if we add (or subtract) the same amount from both sides, it does not affect the inequality

Example: Alex has more coins than Billy. If both Alex and Billy get three more coins each, Alex will still have more coins than Billy.

What If I Solve It, But "x" Is On The Right?

No matter, just swap sides, but reverse the sign so it still "points at" the correct value!

Example: 12 < x + 5

If we subtract 5 from both sides, we get:

7 < x

That is a solution!

But it is normal to put "x" on the left hand side ...

... so let us flip sides (and the inequality sign!):

x > 7

Do you see how the inequality sign still "points at" the smaller value (7) ?

And that is our solution: x > 7

Note: "x" can be on the right, but people usually like to see it on the left hand side.

Multiplying or Dividing by a Value

Another thing we do is multiply or divide both sides by a value (just as in Algebra - Multiplying).

But we need to be a bit more careful (as you will see).

Positive Values

Everything is fine if we want to multiply or divide by a positive number:

Example: 3y < 15

If we divide both sides by 3 we get:

y < 5

And that is our solution: y < 5

Negative Values

When we multiply or divide by a negative number
we must reverse the inequality.

Why?

Well, just look at the number line!

For example, from 3 to 7 is an increase,
but from −3 to −7 is a decrease.

−7 < −3

7 > 3

See how the inequality sign reverses (from < to >) ?

Let us try an example:

Example: −2y < −8

Let us divide both sides by −2 ... and reverse the inequality!

−2y < −8

y > 4

And that is the correct solution: y > 4

(Note that I reversed the inequality on the same line I divided by the negative number.)

So, just remember:

When multiplying or dividing by a negative number, reverse the inequality

Multiplying or Dividing by Variables

Here is another (tricky!) example:

Example: bx < 3b

It seems easy just to divide both sides by b, which gives us:
x < 3
... but wait ... if b is negative we need to reverse the inequality like this:
x > 3
But we don't know if b is positive or negative, so we can't answer this one!

To help you understand, imagine replacing b with 1 or −1 in the example of bx < 3b:

The answer could be x < 3 or x > 3 and we can't choose because we don't know b.
So:
Do not try dividing by a variable to solve an inequality (unless you know the variable is always positive, or always negative).

A Bigger Example

First, let us clear out the "/2" by multiplying both sides by 2.

Because we are multiplying by a positive number, the inequalities will not change.

x−3 < −10

Now add 3 to both sides:

x < −7

And that is our solution: x < −7

Two Inequalities At Once!

How do we solve something with two inequalities at once?

Example:

First, let us clear out the "/3" by multiplying each part by 3.

Because we are multiplying by a positive number, the inequalities don't change:

−6 < 6−2x < 12

Now subtract 6 from each part:

−12 < −2x < 6

Now divide each part by 2 (a positive number, so again the inequalities don't change):

−6 < −x < 3

Now multiply each part by −1. Because we are multiplying by a negative number, the inequalities change direction.

And that is the solution!

But to be neat it is better to have the smaller number on the left, larger on the right. So let us swap them over (and make sure the inequalities point correctly):

Summary

Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.

But these things will change direction of the inequality:

Multiplying or dividing both sides by a negative number

Swapping left and right hand sides

Don't multiply or divide by a variable (unless you know it is always positive or always negative)

Pythagorean Theorem: In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Theorem (Boyaj, 1832; Gervin, 1833).

If two polygons have the same area, then they are decomposable in the same set of polygons.

That is, if two polygons have equal areas, then any of them can be decomposed into a finite set of pieces with which it is possible to reconstruct exactly the other polygon.

Dear Mrs. Miller,

My daughter loves the new online practice site. Using mom's computer is always a fun treat, so she was thrilled to get to practice math facts on it. Please give our thanks to your son! My daughter says, "Thank you so much!"

We have loved Math Mammoth for the past 6 years. I've taught high school math since before I had children, using Foerster's and Jacobs' books in both private schools and homeschool co-ops. When parents with younger children ask what I recommend, I tell them about the great experiences my children have had and how well my oldest was prepared for Algebra. I've even recommended it for remediation for students I tutor who never grasped integers or percents.
Thank you for such a great program!

In Christ,
Jennifer Drury
