These are all either division or multiplication operations. We can go in order, according to the order of operations rules. So, first, -20 * 1/4. :3 Which is the same as -20/4

OpenStudy (anonymous):

-5?

OpenStudy (ipwnbunnies):

Mhm. :) Now, next operation. -5 * 8... Oh I didn't realize you had an answer. Hold on.

OpenStudy (ipwnbunnies):

It is not -7. v.v So, next operation. -5*8 = ?

OpenStudy (anonymous):

-40

OpenStudy (anonymous):

what next?

OpenStudy (ipwnbunnies):

The next operation lol. -40/12. You probably need a calculator. :3

OpenStudy (anonymous):

-10/3

OpenStudy (ipwnbunnies):

Oh, yeah, I forgot about fractions. >_> <_< *dies* And finally, (-10/3)/4 Same as...(-10/3)*(1/4)

OpenStudy (anonymous):

OpenStudy (anonymous):

hello? i need to go fast srry

OpenStudy (anonymous):

-5/6

OpenStudy (ipwnbunnies):

OpenStudy (anonymous):
