Answer 1:
There is some math that you can do to convince
yourself that multiplying 2 negative numbers gives
a positive number. For example, let's say we want
to evaluate 1 x (2 +2). We know that the
expression within the parentheses, 2 + 2,
equals 0, so 1 x (2 + 2) also
equals 0. Using the distributive property,
we know that 1 x (2 + 2) = (1 x 2) + (1 x
2), which we know equals 0. The value
of 1 x 2 is 2, because you simply add
1 two times. This means that (1 x
2) must be equal to positive 2 in
order for the whole expression to equal 0.
This is just one of a few simple proofs you can
use to show this idea.
