Welcome students. In Today's lesson we will be learning about the Order of Operations.

# data[].attributes.body
Our objective for today will be to learn and remember the code PEMDAS for future reference to be able to solve our math problems

# data[].attributes.body
Write and Express Numerical Expressions
5.DA.A1
Use parenthesis and brackets in numerical expressions, and evaluate expressions with these symbols (Order of Operations).

How to solve exponents, add, subtract, multiply, and divide.

The order of operations was first used by a Dutch mathematician named Franciscus Van Schooten in the 1600's. In the 1800's the term "Order of Operations" became more commonly found in books. In the 1920's there was a debate whether or not multiplication should be solve first than division. In the 1960's mathematicians came to and agreement that multiplication would come first than addition, and they also began to add parenthesis to their problems.

The Order of Operations has a secret code that will allow you to remember the order in which to solve the problem in the future. The code is PEMDAS. Please Excuse My Dear Aunt Sally.

Parenthesis | Exponents | Multiplication | Division | Addition | Subtraction

1. Perform the operations inside a parenthesis first

2. Then exponents

3. Then multiplication and division, from left to right

4. Then addition and subtraction, from left to right

Remember to use PEMDAS.

Order of Operations
The rules of which calculation comes first in an expression. Parentheses, Exponents, Multiplication, or Division, Addition or Subtraction
Grouping Symbols
Parentheses ( ), Brackets {}, Absolute Value bars ||or Fraction Bars --that group numbers together.
Factor
A whole number that multiplies with another number to make a third number.
Quotient
The number that is the result of dividing one number by another number.
Addend
A mathematical term that refers to the numbers being added together in an addition problem.
Base
The number that is going to be raised to a power.
Simplify
To remove brackets, unnecessary terms and numbers by performing all possible operations.
Expression
Numbers symbols and operations grouped together that show the value of something.

Product

The result of multiplying a set of numbers.

Dividend

The number being divided in a division equation.
Sum

The result of adding a set of numbers

Difference

The result of subtracting two numbers.

Exponent

A small raised number that shows how many times the base is used as a factor.

Remember what PEMDAS stand for, the order in which it should be used and to solve the following problems.

For this review game we will be using a dice to help complete our problems. Example: The dice is rolled and 5 comes up. 5 will be placed in the first box. The process will continue until the last box which will remain empty until we solve the problem. That box will be where our final answer will go.

The Oder of Operations will be helpful for us in the future. A good example is when we go shopping. Lets say we went shopping for a pair of sock that cost $10 each. Then we decide to stop for some food at Panda Express and the meal is $9 but we have a coupon for a $2 discount. We will find the final prices before and after saving.

(2 x $10) + ($9 - $2)
20 + 9 - 2 = $27 Total after Savings
25 total without saving
We saved $2 with our coupons.
