TASK DEFINITION: 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).
PROBLEM: What is the product of -4 and -42?

SOLUTION: 168

PROBLEM: Calculate 5 - (0 + (3 - 1)).

SOLUTION: 3

PROBLEM: Suppose -s + 5 = 3*r - 22, 5*r + 2*s = 46. Let h = -2 + 5. Suppose 2*u - h*u - 3*j - 1 = 0, 2*j + 10 = 0. Calculate the remainder when u is divided by r.

SOLUTION:
6
