If g > 0 and h < 0, which of the following is always positive?

If g > 0 and h < 0, which of the following is always positive?
A . g × h
B . g + h
C . g C h
D . |h| C |g|
E . hg

Answer: C

Explanation:

A positive number minus a negative number will not only always be a positive number, but will also be a positive number greater than the first operand. g × h will always be negative when one multiplicand is positive and the other is negative. g + h will be positive when the absolute value of g is greater than the absolute value of h, but g + h will be negative when the absolute value of g is less than the absolute value of h. |h| C |g| will be positive when |h| is greater than g, but |h| C |g| will be negative when |h| is less than g. hg will be positive when g is an even, whole number, but negative when g is an odd, whole number.
