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: Suppose -106 = -2*u + s, u - 40 = -5*s + 13. Calculate the remainder when u is divided by 14.

Output: 11


Input: Consider Input: What is 6*(16/20)/(6/5)?

Output: 4


Input: Consider Input: Let h(p) = p + 1. Let y(d) = -2*d - 3. Suppose -3*x + 1 - 4 = 0. Let z(c) = x*y(c) - 3*h(c). Let g be z(0). Solve 0 = 2*s - g + 8 for s.


Output: -4
