Properties of Operations
Grade 6 · Math · Expressions and Equations · Kentucky, USA
Lesson Summary
The commutative, associative, and distributive properties let you rearrange and simplify expressions.
Explanation
Math has useful rules that make calculations easier. The commutative property says you can add or multiply numbers in any order (3 + 5 = 5 + 3). The associative property says you can group numbers differently when adding or multiplying ((2 + 3) + 4 = 2 + (3 + 4)). The distributive property lets you multiply a number across a sum: 3(4 + 5) = 3 times 4 + 3 times 5 = 12 + 15 = 27. These properties help you simplify expressions and do mental math more efficiently.
