Substitute -4 in for W. For #1 parenthesis first so -4 - 4 =-8. Then multiple by 6 so -48 then divide by 8 so -6. Or after doing the parenthesis the 8 on the top and bottom cancel giving -6.
#4 look like this?
-8-4=-12

For #4, -4 squared should be 16 - 4 is 12.
Right, 2 negatives is a positive. Thanks
I did -4 x 2, that why I got the answer I did. I didn’t square it
