Problem 13
Question
Find each sum without the use of a number line. $$-30+(-30)$$
Step-by-Step Solution
Verified Answer
-60
1Step 1: 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.
2Step 2: 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.
