HEY DEAR....
HERE'S YOUR ANSWER⬇
There are a few rules. Some of them are :
# (-)×(+)=(-).
# (-)×(-)=(+).
# (+)×(+)=(+).
# (+)×(-)=(-).
So we know that 6*2=12.
And by following the above rules,
(-6)×(-2)=12.
Any doubts, please ask me in the comments.
I HOPE YOU FIND IT HELPFUL.
@ LB :)

Anonymous: From the distributive law of multiplication we have

a*(b+c) = a*b + a*c

which holds for all real numbers. So it will hold if we put a=-1, b=1 and c=-1 right? let’s do it!

(-1)*(1+(-1)) = (-1)*1 + (-1)*(-1)

1+(-1) = 0 and -1*1 = -1 so we get

(-1)*0 = -1 + (-1)*(-1)
0 = -1 + (-1)*(-1)

rearrange to get

1 = (-1)*(-1)
