Problem 15
Question
Find each sum without the use of a number line. $$-8+(-10)$$
Step-by-Step Solution
Verified Answer
-18
1Step 1: Understand the Problem
We are trying to add two negative numbers together, which are -8 and -10. Since they are both negative, when we add them together, the result will also be negative.
2Step 2: Perform the Addition
When we see a plus sign followed by a negative number, we can replace the combination '+-' with a '-'. Therefore, -8 + (-10) can be rewritten as -8 - 10.
3Step 3: Calculate the Sum
We then proceed with the subtraction operation, which gives us -18. This is the final answer.
