Question

describe and correct the error in finding the difference of -2 and -5.......... -2 - (-5) = -2 + (-5) = -7

Answer 1

In this case, the way the negative was distributed for the -5 is incorrect. So instead of -2+5, it's saying that -2-5 is the same as -2 + -5, Which is isn't in this case. So the error here is the distribution of the -(-5).

The correct way is this:

-2-(-5)

-2+5 = 3
