Multiplication of Rational Numbers
Applying the commutative, associative and distributive properties on multiplication of fractions and rational numbers. Understanding the impact of negative sign in multiplication of rational numbers and applying the same to real-world mathematical problems.
Mapped to CCSS Section# 7.NS.A.2a
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.
