1.prove that positive plus positive is equal to positive
2.prove that negative plus negative is equal to negative


Sagot :

1.  If you sum up the two positive it will end up positive, because of the positive number and the + sign. It will never end up negative, if in case the other number is greater that the one you add up.
2. If you sum up the two negative it will surely end up negative, because they have both equal signs.
