Problem 11
Question
Find each sum without the use of a number line. $$30+(-30)$$
Step-by-Step Solution
Verified Answer
The sum of 30 and -30 is 0.
1Step 1: Recognize Zero Pair
In the expression 30 + (-30), you have a number 30 and its additive inverse -30. These two numbers form a zero pair.
2Step 2: Add Zero Pair
By the principle of zero pairs, whenever you add a number to its opposite (additive inverse), the sum is always zero.
