the order of operation is
B - brackets first , you don't have any
E - exponents, you don't have any
D - division, in the order they come
M - multiplication, in the order the come
A - addition
S - subtraction
so for the first one
32 + 14 - 6 * 40 - 8
= 32+14 - 240 - 8
= 46 - 240 - 8
= -202 , as I had before.
I will do one more, the last one:
= -418, again, not true
The others are also false.
Unless you made an error in typing, the answers do not make sense.
Since in the conversion there is no division, how can each of the answers contain a decimal?
