Chapter 1: Problem 13

Find each sum without the use of a number line. $$-30+(-30)$$

Short Answer

Expert verified
-60

Step by step solution

01

Understand the Problem

The problem is asking to add two negative numbers without using a number line. The numbers to be added are -30 and -30.
02

Addition of Negative Numbers

The rule for adding two negative numbers is to add the absolute values of the numbers and attach a negative sign to the result. So, |-30| + |-30| = 30 + 30 = 60. Because original numbers were negative, the result will also be negative. So, -30 + (-30) = -60.
