Problem 16
Question
Find each sum without the use of a number line. $$-4+(-6)$$
Step-by-Step Solution
Verified Answer
The sum of -4 and -6 is -10.
1Step 1 Understand the concept
In general, adding together two negative numbers will always result in a negative number. This is because a negative number is less than 0, and adding something less than 0 will make the total less.
2Step 2 Find the sum
To find the sum, you would disregard the negative sign and proceed with the addition as if they were normal positive numbers. So, without considering the negative signs initially, \(4 + 6 = 10\).
3Step 3 Apply the negative sign
However, we disregarded the negative signs initially. We must apply them now to get our final answer: -10. Hence, \(-4 + (-6) = -10\).
