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: How many millilitres are there in 9.081666 litres?
Example Output: 9081.666

Example Input: Suppose -2*m - 2*h + 36 = 12, -2*m + 42 = -4*h. Suppose -2*u = 5*x - 40 - 2, -u = x - m. Solve 14 = 4*d + 2*s, -s = 2*d - 6*d + u for d.
Example Output: 3

Example Input: What is prob of sequence nrzz when four letters picked without replacement from {z: 5, n: 5, r: 2}?
Example Output:
