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: Suppose a - 6*a + 3*j + 321 = 0, -342 = -5*a - 4*j. What is the greatest common divisor of 165 and a?

Output: 33


Input: Consider Input: What is 8 divided by -5?

Output: -8/5


Input: Consider Input: Let z(p) = 5*p**2 - p. Suppose 28 = 2*r + 3*v, -2*r + 4*v - 28 = -4*r. Let s be (-1)/(-4) - r/(-8). What is the smallest common multiple of 4 and z(s)?


Output: 36
