-2 * -6=?
Find the (solution!) before putting the 12. Use the associative law. Also remember (- * - = +)

Dont give the answer find the (solution!) and the answer!
2006-09-20 11:15:16 · update #1
here's some rigor:
-2*-6 = (-1)(2)*(-1)(6) by (-1)a=-a, a lemma to prove, x2
=((-1)(2)*(-1))* (6) by associativity, be careful
=((2)(-1) * (-1))* (6) by commutative
=((2) * ((-1)(-1)))* 6 by associativity
=(2*1)*6 by proving -1*-1 = 1, another lemma
=2*6 by 1 identity
=12

+12
-1*2*-1*6 = -1*-1 *2*6 = +1*+2*+6 = +12

What do you mean by "putting the 12." This problem has nothing to do with the associative property. The solution is 12.

The product of two negatives is a positive, so the answer is 12. I don't understand your instructions below the problem.

-2 * -6 = (-2)*(-6) = [(-1)(2)][(-1)(6)]=(-1)(-1)(2)(6) = (+1)(6) = +12

first off. a negative times a negative always equals a positive and
for God sake everybody know how nuch is 2 x 6. it is 12
so your answer is 12

That would be a positive twelve. Multiply the two and six and ebcause they are the same sign, you come out with a positive answer.

-2 * -6
(-1)(2) * (-1)(6) if a=-1
a2 * a6
a*a*2*6
a^2*2*6 a=-1 then a^2 = (-1)^2 = -1*-1=1 if (-*-=+)
(1)*2*6
12
I hope it helps....
