Algebra Word Problem Definitions

Basic

* = Multiplication
x = Variable
+ = Addition
- = Subtraction
/ = Division
( ) = Do whats inside 1st if applicable before doing anything else

ex: (8 + 7)/3 = (15)/3 = 5 which is the same thing as 8/3 +7/3 = 15/3 or (x+7)/3 = x/3 + 7/3 when x = 8

^ = Exponent

ex: 3^3 = 3 * 3 * 3 = 27 5^2 = 5 * 5 = 25

5(3) means multiply 5 * 3 = 15
5(1 + 2) same thing but you would usually just add the whats in the brackets 1st making 5(3) and again 15 or you could multiply across 5(1) + 5(2) = 5 + 10 = 15

6/3 is the same thing as 6 * 1/3 or x/y = x * 1/y
