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:
What is 0 + 5 - 15 - -5?

Ex Output:
-5


Ex Input:
Suppose 3*f + n = -0*n + 13, -5*n + 20 = 0. Suppose f = 3*d - 3. Suppose 6 = -p + 7. What is the remainder when d is divided by p?

Ex Output:
0


Ex Input:
Suppose 2*g + 2*g + 5*b = 165, 0 = 5*g - 4*b - 237. Let a = 75 - g. What is the remainder when a is divided by 11?

Ex Output:

8
