Why is it negative?

-3 * 2, is saying, "negative 3 sets of two."

I am not allowed to give you the answer, but the equation is now: x - 6 = -10 Add six
anonymous
  • anonymous
the -3 can be seen as +(-3), so you work with an negative number. The problem is "how you isolate x?"
anonymous
  • anonymous
so add 6 to -10? -4
anonymous
  • anonymous
