You would use the reverse operation for a negative integer being added or subtracted.

To add a negative integer, subtract its absolute value (positive value).

Example : 4 + (-3) = 4 - (3) = 1

To subtract a negative integer, add its absolute (positive) value.

Example : 4 - (-2) = 4 + 2 = 6

Beginning with a negative, adding a negative increases the negative value.

Example : (-4) + (-3) = -7

Subtracting a negative reduces the negative value.

Example (-4) - (-1) = (-3) * this is the same as (-4) + 1 = (-3)

There's no fun in playing it safe. Why not try something a little unhinged?
