Prove that a negative times a negative equals a positive
In this lesson, you will learn how to prove that a negative times a negative equals a positive by using the distributive property.
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 realworld contexts.
