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).

Example Input: Let u(f) = 2*f**2 - 5*f + 7. What is the remainder when u(7) is divided by 12?
Example Output: 10

Example Input: What comes next: 59, 84, 121, 170, 231?
Example Output: 304

Example Input: Let j = 12 - 10. Suppose -5*u + j*u + 9 = 0. Solve -13 = -2*g - u for g.
Example Output:
5
