Combining like terms
Learn how to combine like terms (with negative numbers and variables), including more complex problems involving the distributive property.
In simple addition we learned to add all the numbers together to get a sum. In algebra, numbers are sometimes attached to variables and we need to make sure that the variables are alike before we add the numbers.
We've learned about order of operations and combining like terms. Let's layer the distributive property on top of this.
This example of combining like terms in an expression get a little hairy. Listen closely.
Simplify algebraic expressions by combining like terms. Coefficients on some terms are negative.
Practice combining like terms using the distributive property. These problems involve adding and subtracting negative numbers.
Learn how to simplify algebraic expressions by combining like terms. The expressions in this video have decimal and fraction coefficients.
Practice combining like terms for expressions that have rational coefficients. This requires adding and subtracting fractions.
