Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a real-world situation. For example, for an account balance of –30 dollars, write |–30| = 30 to describe the size of the debt in dollars
Understand subtraction of rational numbers as adding the additive inverse, p
). 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.
