remember a 6 is positive times a negative times a negative will give you a postive number

OpenStudy (raffle_snaffle):

because -2*-3 = +6

OpenStudy (biue):

ok

OpenStudy (anonymous):

B because the end result is negative. 3 - signs equal a negative number.

OpenStudy (raffle_snaffle):

and a +6 * (+6) = + 36

OpenStudy (biue):

stop giving direct answers

OpenStudy (biue):

I WANNA LEARN DAMMNIT

OpenStudy (raffle_snaffle):

just remember this Blue -*- = + -*+ = - +*+ = +

OpenStudy (anonymous):

@Blue. Okay. So understand this. 2 plus signs equal a positive number 2 minus sign equal a negative number 3 minus sign equal a negative number. a minus and a plus equal a negative number. + in odd and even numbers produce +ve integers - in odd numbers produce -ve integers - in even numbers produce +ve numbers. if you are multiplying more than 2 numbers with different signs, - in even and + in even/odd result in +ve integers - in odd and + in even/odd result in -ve integers
