**Reiny**, Sunday, August 21, 2011 at 12:07pmthe order of operation is

BEDMAS

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:

32/6*14+32-8

= 32+6-14*32-8

= 32+6-448-8

= -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?

=
