How can you use addition rules to solve subtraction problems with integers?

Not entirely sure about what the question is asking, but explanation of what I think it is asking.

Step-by-step explanation:

There are three basic rules of addition.

Positive + Positive = Positive Ex: 1+1=2

Negative + Negative = Negative Ex: -2+-2=-4

Negative + Positive = Positive or Negative depending on the value.

Ex= 1+(-2)=(-1)

Ex=2+(-1)=1

So subtraction problems can be turned into addition problems.

For example:

4-2 is the same as 4+(-2).

Or -5-7 is the same as -5+(-7).

Hope this makes sense.

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
