Do a negative plus a plus a negative equal a posiotive?

Answer 1

No. A negative plus a negative never equal a positive. That property only works in multiplication and division.

When you add a negative basically what your doing is subtracting the opposite of the number. For Example;

2+ (-6) = ?

what you would do in this case is just subtract positive six from positive two witch would be negative 4, so the answer to that problem would be -4.

Heres another example with two negatives;

-3 + (-3) = ?

What you would do in this case is just add positive 3 plus 3 which would be 6, but since its a negative number it would be -6 because you are going backwards on the number line (in this case starting at -3 and moving back 3 spaces) when you subtract negative numbers.
