Let’s you multiply a sum by multiplying each addend separately and then add the product

allow use to represent things like distance, time, interest, and slope as variables in an equation

You multiply both sides of the equations by the same number

a statement that the values of two mathematical expressions are equal

The order doesn’t matter you’ll always get the same answer

It will always equal 0

that if the same amount is added to both sides of an equation

You divide both sides of the equation
