7.NS.2a

Grade 7 · The Number System

Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (—1)(—1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
