Question

13. Reason abstractly. If you subtract a negative number from
another number, will the other number increase or decrease?
Explain.

Answer 1

Subtracting a negative number is like removing debt. When you remove debt, you effectively gave someone money and the value of their bank account increased.

Another answer is that “subtraction is addition of the opposite,” so subtracting a negative number is really adding a positive number, which again causes the other number to increase.

Answer 2

Hi! I'm happy to help!

When you remove a negative, you are removing the thing that decreases, which causes stuff to increase.

I hope this was helpful, keep learning! :D
