OVERVIEW:

7.NS.A.1b / 7.NS.A.1c - Addition and Subtraction of Rational Numbers (Part 1 of 2) is a free educational video by MathwithMrAlmeida.It helps students in grades 7 practice the following standards 7.NS.A.1.B,7.NS.A.1.C,.

This page not only allows students and teachers view 7.NS.A.1b / 7.NS.A.1c - Addition and Subtraction of Rational Numbers (Part 1 of 2) but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

1. 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..

2. 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..
