7.NS.A.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.
1) Use absolute value to express in simplest form: |
2) What number was added to 8 to get a sum of -4?
|
7.NS.A.1.C Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q).
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.
