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).

Input: Consider Input: Let l = 1 + 7. Solve 4 + l = 3*s for s.

Output: 4


Input: Consider Input: Suppose 6*l - 22 = 56. Calculate the remainder when 100 is divided by l.

Output: 9


Input: Consider Input: Let b(f) = f**3 - 2*f**2 - f + 2. Let s be b(3). What is the greatest common factor of 8 and s?


Output: 8
