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: What is ((8/6)/(-4))/1?

Output: -1/3


Input: Consider Input: Suppose p - 4*p = 0. Suppose -4*v + 0*v + 17 = -l, 4*l + 4 = p. Suppose -3*m + 55 = -17. Solve -5*r + v = m for r.

Output: -4


Input: Consider Input: Work out 0 * 338.1.
