Answer:
2
Step-by-step explanation:
This is the answer because:
1) First, we have to add 16 and 28 which is 44
16 + 28 = 44
2) Next, we have to add 44 and -42, which will be 2 because whenever we have to add or subtract integers, we are supposed to multiply the signs, and then we have to put the sign of the greater number. In this case, it would be:
44 + (-42) = 44 - 42 = 2
Hope this helps! :D
