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: What is the least common multiple of 40 and 2 - (-52)/(-28) - 209/(-7)?

SOLUTION: 120

PROBLEM: Let b(l) = l**3 - 2*l**2 - 3*l. Let g be b(3). Solve g*f + 15 = -3*f for f.

SOLUTION: -5

PROBLEM: Let p be 1 + 0 - 0 - -1. Suppose -36 = 3*o - 5*o - 4*c, -5*o = p*c - 82. Suppose v - 188 = -4*v + 3*g, -o = -4*g. What is the remainder when v is divided by 21?

SOLUTION:
