The Distributive Property
Grade 7 · Math · Expressions and Equations · Indiana, USA
Lesson Summary
Multiply a number across terms inside parentheses to remove grouping symbols.
Explanation
The distributive property says a(b + c) = ab + ac. You multiply the factor outside the parentheses by every term inside. This property also works with subtraction: a(b − c) = ab − ac. After distributing, you can often combine like terms to simplify further. The distributive property is one of the most frequently used tools in algebra.
