Thread: word problem... question

shouldn't it be 3 - 1 = 2 and not 3 - 3 = 0 because it's asking for the greatest possible value of h - g ???

What's the entire problem?

here my bad

That's a poorly worded problem, as -21 is a factor of 21, we could say the maximum value of h - g is 3 - (-21) = 24.

Even if we restrict ourselves to positive integral factors, your solution 3 - 1 = 2 is better than the choice given.
