to do as much work as possible
simplify
Must have an equal sign Example: 7(3) = 21
equation
no equal sign Example: 2 + 7
expression
the order in which we solve equations (PEMDAS: parenthesis, exponents, multiply or divide, add or subtract)
order of operations
All whole numbers and their opposites
integers
When you add the opposite, you get zero
Example: 2 + -2 =0
additive inverse
distance from zero
absolute value
answer to an addition problem
sum
you can switch the order in which you add or multiply without changing the answer.
