Essential Understanding
The sign of a product is determined by the signs of the factors in a multiplication expression.
Standards7.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.
7.NS.A.2c Apply properties of operations as strategies to multiply and divide rational numbers. |
