Math Competition 2
It is the day of the Math Competition, Felipe got off to a bad start, but now has a chance to be in the top 10 of all 5 schools, and get in the finals. He once again found himself tied for the last spot, this time with a girl named Rico. Same as last time, the two get one question to answer the fastest, the winner getting to go on to the finals the next day.
Suppose that each distinct letter in the equation MATH = COU + NTS is replaced by a different digit chosen from 1 through 9 in such a way that the resulting equation is true. If H=4, how many working options are there?

Answer
4798 + 526 = 1324
796 + 528 = 1324
598 + 726 = 1324
596 + 728 = 1324
Rico choked on her pencil, giving Felipe the win by default.
