Adding a positive and a negative is the same as just subtracting.

One oreo PLUS negative one oreos = zero oreos.

1 + - 1 = 1 - 1 = 0

6 + - 2 = 6 - 2 = 4

3 + - 5 = 3 - 5 = -2

Also, adding a negative is the same as subtracting a positive.

6 - + 2 = 6 - 2 = 4

[Unless you were talking about this thing: ± , in which case, just split it into two different problems.]

-------------------------------

area of a triangle = (1/2) * (base) * (height)
