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: Two letters picked without replacement from gueugfuwu. Give prob of sequence wg.

SOLUTION: 1/36

PROBLEM: Solve -k = -4*a + 15, 0 = 6*k - 10*k + a + 15 for k.

SOLUTION: 5

PROBLEM: Let f(p) = 5*p**3 - p**2 + p - 1. Let b be f(1). Suppose -2*u + 2*y = 3*u - 10, -b*u - 3*y - 15 = 0. Solve u = 4*j - 3*j for j.

SOLUTION:
0
