Answer:
-6.29
Explanation:
Add two negative integers together is just as simple as two positive integers together.
Let's for a little bit ignore that negative. What is 4.058 + 2.232? 6.290 or just 6.29. Now slap a negative in front of it!
Your answer is -6.29.
Different rules arise when adding a negative integer with a positive integer. We can cross the bridge when we get there :)
