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).

Input: Consider Input: -774 divided by -3

Input: Consider Input: Solve -3*w - 4 = -h - 8*w, 4*h = -2*w - 2 for h.

Output: -1


Input: Consider Input: Suppose -2*u + 2*o + 60 = 0, 4*u + 0*o = -5*o + 102. Calculate the highest common divisor of u and 42.
