Adding two rational numbers if a pair of Addends has the opposite signs then the sun will have the sign of the addend with the with the greater  value among the two.

These examples can better illustrate this concept:
Example 1:
23 + (-3) = 20 (The greater among the two is positive and the result is also positive)

Example 2:
-23 + 3 = -20 (The greater among the two is negative and the result is also negative)

The answer would be 24mm
