Question

Answer 1

5

Explanation:

-*-=+

-*+=-

+*+=+

-3-(-8)=5

-3+8=5

Answer 2

5

Explanation:

When you have a negative next to a negative, you can turn it into a positive. For example the -(-8) would now be +8. This is called the airplane strategy because it forms a airplane if you flip you sheet of paper or your device.

From here, we have -3+8.

Now we subtract since each value has a different sign and we get +5.

Hope this helps!! :)
