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: Work out -0.4 + 7169.
Example Output: 7168.6

Example Input: Let x = 59 + -51. What is the lowest common multiple of x and 22?
Example Output: 88

Example Input: Suppose -4*d + d = d. Solve z - 4*g - 15 = d, -2*g = 3*z - 0*g + 11 for z.
Example Output:
-1
