Answer:
26
Step-by-step explanation:
When we subtract a negative it is like adding
(-16) - (-42)
(-16) + (42)
Re arranging the order
42 -16
The - 42 is going to give trouble.
Two minus signs multiplied together give a plus. In fact any number of even minus signs (2,4,6,8, 1000) multiplied together make a plus.
(-16) + 42 = 26
