Essential Understanding
Subtracting a number is the same as adding that number’s additive inverse.
Standards7.NS.A.1c 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.
7.NS.A.1d Apply properties of operations as strategies to add and subtract rational numbers. |
