Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If π and π are integers then β(π/π) = (βπ)/π = π/(βπ). Interpret quotients of rational numbers by describing real-world contexts.

Describe situations in which opposite quantities combine to make 0.

Understand π± + π² as the number located a distance |π²| from π±, in the positive or negative direction depending on whether π² 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.

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 (β 1)(β 1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.

Understand subtraction of rational numbers as adding the additive inverse, π± β π² = π± + (βπ²). 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.
