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 t(n) = n**2 + 8*n + 3. Let h(j) = -j**3 + 3*j**2 - 4*j + 2. Let a be h(4). Let z = -8 - a. Calculate the remainder when z is divided by t(-9).

Ex Output:
10


Ex Input:
Solve 0 = 3*f - 2*x - 11, 0 = 2*x - 7*x - 5 for f.

Ex Output:
3
