Apply properties of operations as strategies to add and subtract rational numbers.
Understand subtraction of rational numbers as adding the additive inverse, π± β π² = π± + (βπ²). 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.
Understand π± + π² as the number located a distance |π²| from π±, in the positive or negative direction depending on whether π² 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.
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.
Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
