What does a negative minus a positive equal?
A negative subracting a positive will end up as a negative.
Explanation:
If you have 3 negatives, you cannnot take 3 positives from it,
so you need to add 3 zeros, (which are both negative and positive),
to the negative side. The number zero means nothing, so it will not
alter the question.
KEY
_ =negative + =positive _+ =zero
_ _ _ needs _+ _+ _+ to subract + + +
Once you take the 3 positives from the negative side, you will
be left with 6 negatives
_ _ _ _+_+_+ minus + + + leaves you with _ _ _ _ _ _
*NOTE*
You may be thinking, "But the zero did count! It's symbol left a
mark on the answer!". Wrong. Zero in math means nothing, and that
is how it will stay. You only needed it because it had the positive
sign you were looking for. But because it is both positive and
negative, you will be left with a negative when you take away the
positive, and a positive when you take away the negative. This is
why a positive subracting a negative will equal a negative.
