$0$
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 $|-64|=64, |64|=64, 64=64$ $64-64=0$ Both -64 and 64 have the same absolute value, so either way (choosing -64 or 64 as the larger value) will result in the answer equaling $0$.
