Intro To Algebra By: Carolyn Barone

2
**Opposite Signs The opposite of multiplication is division.**

The first step to understanding algebra is knowing which operations cancel each other out. The opposite of multiplication is division. The opposite of subtraction is addition.

3
Combining Like Terms Step 2 in learning algebra is knowing how to combine like terms. This means, if two or more terms are of the same type, we can combine them to make only one term of each type. For now, we’re only going to look at 2 types:

**Solving Algebraic Equations**

In order to solve algebraic equations, we first combine like terms, and then solve for x by using opposite signs. If we perform an operation to one side of the equation, we must perform the same operation to the other side. 1) Combine these like terms 2) Add 8 (opposite of subtracting 8) 3) Divide by 6 (opposite of multiplying by 6) Notice our ending goal is to get x by itself.
