Math- Simplifying Like Terms

Recently, we have been learning about how to simplify like terms. This is how you combine like terms.
For example:
 112x + 13x - 12 + 13

First, you have to know what are like terms. Like terms will depend on the exponent, variable and what kind of terms there are in your expression. There all variable terms, there are terms that are regular numbers. In order to know what kind of terms to combine first, use the first kind of term in the expression.

112x + 13x

Always use the sign that is before the term to know if it's a positive or a negative. In this case, the expression is positive. So 112x + 13x is equal to 125x. You add the numbers and leave the variable.
Then you must figure out the second part of your simplified expression.

-12  + 13

Remember to keep the sign before the term. -12 +13 is equal to 1.

Final Answer:

125x + 1
