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).

Ex Input:
Let s(z) = -z**3 + 4*z**2 + 7*z + 2. Let g be s(5). Suppose -3*h + 155 + 526 = 0. Let b = 323 - h. What is the highest common divisor of g and b?

Ex Output:
12


Ex Input:
Solve -12*b = -35*b + 92 for b.

Ex Output:
4


Ex Input:
Suppose -3*o + 49 - 7 = 0. Suppose 4*w = -l - o, -5*w - 43 = -3*l - 0*l. Solve 4*m - 2 = l for m.

Ex Output:

2
