TASK DEFINITION: Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).
PROBLEM: Let f be (4 + -6)*1/2. Let u be (-15)/(-6)*(-2)/f. Suppose 35 = 2*m - u*g, -5*m + 0*g = 3*g - 72. What is the tens digit of m?

SOLUTION: 1

PROBLEM: Let u = -26 - -12. Let d = u - -24. What is the units digit of (2 - d)*2/(-4)?

SOLUTION: 4

PROBLEM: In base 14, what is 2 - -129?
