Q:

Negative plus a positive equals

A) negative	B) positive
C) zero	D) Can't be determined

Answer & Explanation Answer: D) Can't be determined

Explanation:

We know that a negative value plus a positive value always count backward and the sign depends on the bigger value sign.

When you are adding a negative number to a positive number, then the value counts backward and takes the sign of the biggest number.

For example::

Adding -5 and +2

-5 + 2 = -3 (big number is 5 and its sign is '-')

Adding -3 and +5

+5 + (-3) = 5 - 3 = +2(big number is 5 and it has sign '+').
