OpenStudy (caozeyuan):

do you know that you can pull negative signs to the front

OpenStudy (fibonaccichick666):

Count the number of minus signs. If even, positive If odd, negative

OpenStudy (lowkey.s):

yes

OpenStudy (lowkey.s):

C

OpenStudy (caozeyuan):

so (-2)(4)(-6)(-3)=-1*-1*-1*2*4*6*3

OpenStudy (lowkey.s):

or D

OpenStudy (fibonaccichick666):

what do you find?

OpenStudy (lowkey.s):

that negative

OpenStudy (caozeyuan):

first 3 gives you -1, last 4 is postive, so result is negative

OpenStudy (lowkey.s):

So D or C?

OpenStudy (fibonaccichick666):

good, so now, you narrowed it down to C or D, so take a look. Is a + times a - positive or negative?

OpenStudy (lowkey.s):

postive

OpenStudy (fibonaccichick666):

a positive times a negative?

OpenStudy (caozeyuan):

it is D because C says -6*-3 is negative, which is incorrect

OpenStudy (lowkey.s):

Wait what?

OpenStudy (lowkey.s):

So D right?

OpenStudy (fibonaccichick666):

yes.

OpenStudy (caozeyuan):

im saying that C is incorrect, so you should choose D

OpenStudy (lowkey.s):

oh oki!

OpenStudy (fibonaccichick666):

but you need to remember that a positive times a negative yields a negative.
