This document contains a mental math review worksheet with 12 problems for students to solve using properties like the distributive property. The problems include expressions like 3(2 + 5), 4(3 + 6), and 5(7 + 4) that require distributing multiplication over addition. Step-by-step workings are shown for the first four problems as examples. Common properties like associative, commutative, and distributive are defined at the bottom.
