Let's use the number -5, and look at the simple multiplication table:
-5 x 2 = -10
-5 x 1 = -5
-5 x 0 = 0
As you can see, the numbers on the right are being increased by 5 every time. So
-5 x -1 is 5
Another helpful way to think of it is common sense.
If I say to you, "Eat," I am telling you to do something (+)
And if I say "Do not eat," I am telling you to do the opposite (-)
But if I say "Do NOT not eat," I am telling you not to starve, and therefore to eat (+)
