Part 1. 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).
Part 2. Example
Let y = -74 - -79. Solve 0 = -y*q - 13 + 3 for q.
Answer: -2
Explanation: Solving the two equations, we find that the value of q is -2. The solution can be obtained by simply solving the equations one after another using substitution.
Part 3. Exercise
