Math Grade 7 Quiz Understanding Subtraction of Rational Numbers – 7.NS.A.1.C
The standard CCSS.MATH.CONTENT.7.NS.A.1.C educates students about the concept of subtraction in terms of rational numbers. Subtraction is understood as the process of adding the additive inverse, i.e., for any numbers p and q, p – q can be represented as p + (q). An essential takeaway is that the distance between two numbers on a number line is the absolute value of their difference. This principle is crucial and finds several applications in realworld contexts.
