Problem 12
Question
Find each sum without the use of a number line. $$15+(-15)$$
Step-by-Step Solution
Verified Answer
The sum of \(15\) and \(-15\) is \(0\).
1Step 1: Identify the numbers
The two numbers involved in the operation are \(15\) (positive) and \(-15\) (negative).
2Step 2: Perform the operation
Adding a negative number to a positive one essentially means subtracting the absolute value of the negative number from the positive number. So, the required operation becomes \(15-15\).
3Step 3: Compute the result
Upon performing the subtraction, we obtain \(0\).
