$0$

Work Step by Step

Adding Two Numbers with Different Signs: Step 1: Find the larger absolute value minus the smaller absolute value Step 2: Use the sign of the number with the larger absolute value as the sign of the sum $|18|=18, |-18|=18, 18=18$ $18-18=0$ Both 18 and -18 have the same absolute value, so either way (choosing -18 or 18 as the larger number) will result in the answer equaling $0$.
