In class we took notes:

Order of Operations:

-Anthmetic operations(x, ,-,+) must be solved in a particular order. We can use the acronym "PEDMAS" to help remeber the order. Brackets/Parenthesis hold an operation together and bracket holed a number.
Rules:-Evalute expressions within parenthesis first (brackets) P ( )
-Evaluate expressions with exponents next
-Multiply and Divide from left to right in orded of what comes first M/D
-Add and Subtract from left to right in order of what comes first A/D



Here are some examples of what you have to do.
3 2
Ex. 2+8x22 +3
8+8x4+3
8+32+3
40+3=
43
