Answer: for -10 + 4 the answer is -6
for -7 - 11 the answer is -18
Step-by-step explanation:
For -10+4 all you do is start at -10 and go up 4 to -6 (-9, -8, -7, -6)
and for -7 - 11 you start at 7 and just go down (but the numbers get bigger) to -18 (-8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18)
