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 k(f) = 8*f. Let u(l) = -l**2 + 5*l - 1. Let r be u(4). Let v be k(r). What is the greatest common factor of v and 36?

SOLUTION: 12

PROBLEM: Suppose g + x - 9 = 0, -30 = -5*g + x - 9. Solve 4 - 9 = -g*h for h.

SOLUTION: 1

PROBLEM: Let h(k) be the third derivative of k**4/24 - 4*k**3/3 + k**2. Let z be h(13). Solve -2*l = -z*l for l.

SOLUTION:
