Problem 17
Question
Find each sum without the use of a number line. $$-0.4+(-0.9)$$
Step-by-Step Solution
Verified Answer
The sum is -1.3.
1Step 1: Understand the problem
The problem is asking to add two negative numbers. It is important to note that the addition of two negative numbers results in a negative number as well.
2Step 2: Add the absolute values of the numbers
Forget about the negative signs for a moment, and just add the absolute values of 0.4 and 0.9. This results in 0.4 + 0.9 = 1.3.
3Step 3: Attach the negative sign
Remember from step 1 that the sum of two negative numbers is a negative number. So, the sum is -1.3.
