How do you subtract integers?

like - 81 - (-34)

-47

Step-by-step explanation:

For this problem, we can use the rule "two negatives make a positive".

-81 - (-34)

= - 81 + 34

If you subtract 34 from 81, you find the opposite positive/negative answer.

81 - 34 = 47

Change all of the positive/negative signs:

-81 + 34 = - 47
