Use Additive Inverses

(B) Identify a number, its opposite, and its absolute value

(D) Generate equivalent expressions using the properties of operations: inverse, identity, commutative, associative, and distributive properties.

(Y6) Investigate everyday situations that use integers. Locate and represent these numbers on a number line (ACMNA124)

(Y7) Solve simple linear equations (ACMNA179)

7.NS.1.A 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.

7.NS.1.B 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 real-world contexts.
