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: Suppose 56 = 113*r - 109*r. Let z = 22 - 10. Calculate the smallest common multiple of z and r.

SOLUTION: 84

PROBLEM: Let c = 4 - 2. Suppose 0 = n + c*n - u - 27, -3*n + 18 = 2*u. Suppose 3*p - n = 4. Solve 0 = 3*w - p - 2 for w.

SOLUTION: 2

PROBLEM: Let j(g) = -g**2 + 15*g - 26. Let s be j(9). Let b be 1/((-1)/(-70)) + 0. Calculate the highest common factor of b and s.
