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 = -26 - -12. Let d = u - -24. What is the units digit of (2 - d)*2/(-4)?
Example Output: 4

Example Input: Suppose i = w - 15 + 48, -100 = -4*i - 4*w. Let f = -3 + -4. Let k be (-9 - -1)/(5 + f). Solve -4*h - k*v = v - i, 0 = -5*h + 4*v - 15 for h.
Example Output: 1

Example Input: What is 7025 to the power of 1/8, to the nearest integer?
Example Output:
3
