Additive Inverse
Representing the difference between two numbers using the additive inverse of a number and applying the same to real-world word problems. Identifying the number line that represents the numerical statement of two numbers that have an additive inverse and vice versa.
Mapped to CCSS Section# 7.NS.A.1c
Understand subtraction of rational numbers as adding the additive inverse, p – q = p + (- q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
