Math Expressions vs Equations | CAVEMAN CHANG

Expressions are combinations of numbers, variables, and mathematical operations. Math operations are anything from addition, subtraction, multiplication, division, square root, etc. Expressions have no problems, questions, or anything to solve. The only thing you can do with expressions is to simplify it by combining like terms.

Equations are a comparison between expressions. You have one expression equal another expression. In an equation, you can simplify the expressions by combining like terms to solve it. Equations usually have a problem for you to solve which includes finding the value for a variable. The point is to solve the equation so that it is true.

Practice Problems:
Level 1: 5x-7+3x+2+10-2x simplified is 6x+5.
Level 2: Given 7(K+3)=56, K is 5.
Level 3: (3x+10)+(4x+4) simplified is 7x+14 or 7(x+2). Given (3x+10)+(4x+4)=0, x is -2.
