Absolute value needs to be found when you see a number, positive or negative, in between two lines ( |#| ). Absolute value is always positive.

EXAMPLES:

|-3| = 3
The absolute value of -3 is positive 3. This is because -3 is 3 places from 0.

|285| = 285
The absolute value of 285 is 285. This is because 285 is 285 places from 0.]]> 2020-10-15 18:44:18 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/833610958 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/836814017   When adding integers, the expression can be solved by adding or subtracting. In an addition expression with numbers that are the same sign (2 positives or 2 negatives), just add the numbers together and keep the sign (positive or negative). In an addition expression with two numbers that have different signs (1 positive 1 negative) , solve by subtracting the two numbers by each other and keep the sign of the greatest number in the expression.
  

   When subtracting integers, the rule “keep, change, opposite” is used. In a subtraction expression; the first number stays the same, the operation is CHANGED from subtraction to addition, and the second number is flipped (negative to positive or positive to negative). After “Keep, Change, Oposite” the problem can be solved using the rules of addition with integers.

EXAMPLES:

-19 + 12 = -7
This is an addition problem with numbers that have two different signs. I subtracted 19 and 12 to get 7, I then made the answer a negative number because the negative team (-19) has more players Than the positive team (12).

-52 - (-24) = -28

In order to solve this subtraction problem, I used Keep, Change, Opposite. I KEPT the first number, CHANGED the operation, and made the second number the OPPOSITE sign.]]> 2020-10-16 19:32:57 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/836814017 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/837943710 Exponents are numbers that look like this, 4^5. Exponents are repeated multiplication just like how multiplication is repeated addition. When solving an exponent, the base number is multiplied by itself however many times the exponent number says. 

EXAMPLES:

5^3 = 5x5x5 = 125

10^7 = 10x10x10x10x10x10x10 = 10,000,000]]> 2020-10-17 19:59:13 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/837943710 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/838953101 The square root of a number is (A)x(A). Square root needs to be found when a number is inside of \/———.

EXAMPLES:

  ______
\/  25   = 5

The square root of 25 is 5 because 5x5 = 25

  ______
\/  49   = 7

The square root of 49 is 7 because 7x7 = 49]]> 2020-10-18 16:05:34 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/838953101 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/841563387 In order to solve a word problem that has positive and negative integers, the numbers and operation need to be found. Once you figure out the expression that represents the word problem, the problem can be solved.

EXAMPLES:

PROBLEM: In Ontario it is -2 degrees outside. In Massachusetts it is 24 degrees outside. What is the difference between the temperature in Ontario and the temperature in Massachusetts?

EQUATION:  24 - (-2) = 26


PROBLEM: There are 6 kayaks that are 4 feet and 1 kayak that is 3 feet. If all the kayaks were to be lined up from tip to tip, how long would the line of kayaks be?

EQUATION: (6X4)+(1X3)= 27 feet]]> 2020-10-19 15:43:31 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/841563387 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/845710852 When solving a multi-step problem, the acronym GEMS needs to be used. GEMS stands for G-Groupings, E-Exponents, M-Multiplication & Division, S-Subtraction & Addition. Multi-step problems should be solved in the order of GEMS.

EXAMPLES:

PROBLEM:
4X(4+8)-6=42

PROBLEM:
6^2+4X8=320]]> 2020-10-20 16:48:53 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/845710852 lgswirbalus20261 https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/849528602 When evaluating expressions with variables, the variables are replaced with selected numbers. After the variables are replaced, the problem can be solved.

EXAMPLES:

PROBLEM:
A=5
3XA = 3X5 = 15

PROBLEM:
B=12

In both multiplying and dividing, if there is an odd number of negative numbers in the expression, then the answer will be negative. If there is an even amount of negative numbers then the answer will be positive. The expressions should be solved like regular multiplication and division problems.

Distance is how far something travels, rate is how far something travels in a certain amount of time, and time is how long it takes for something to travel a certain distance. In a word problem, 2 of the variables will be given but the third one needs to be found. When R and T are given, they need to be multiplied to find D. If D and R or T are given, then D is divided by R or T to find the third variable.

EXAMPLES:

PROBLEM:
D= 500 miles  T= 5 hr
500/5=100 R=100

PROBLEM:
R= 37 mph T= 3 hr
37x3=111 D= 111 miles]]> 2020-10-23 14:59:14 UTC https://padlet.com/lgswirbalus20261/5f5cv5wk9gee7u0v/wish/856079441
