Understand the additive inverse
In this lesson, you will learn the additive inverse by combining opposite quantities.

Add integers using a number line
In this lesson, you will learn how to add integers by using a number line.
Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged; and understand p + q as the number located a distance q from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing realworld contexts.
