Task: You are supposed to identify the category of a high-school level math question. There are five possible categories (1) algebra (2) arithmetic (3) measurement (4) numbers, and (5) probability. Use the following guidelines: (1) 'algebra' questions will typically contain letter variables and will ask you to find the value of a variable (2) 'arithmetic' questions will ask the sum, difference, multiplication, division, power, square root or value of expressions involving brackets (3) 'measurement' questions are questions that ask to convert a quantity from some unit to some other unit (4) 'numbers' questions will be about bases, remainders, divisors, GCD, LCM etc. (5) 'probability' questions will ask about the probability of the occurrence of something. A question must belong to only one category.
Categories: Question Understanding
Domains: Mathematics
Reasoning: Scientific Reasoning; Mathematics

Positive examples:
input: Suppose -d - 13 = -n - 0, 0 = 2*d + 2. Solve 2*x = -10 + n for x.
output: algebra
explanation: This is a system of three linear equations, clearly an 'algebra' question. Standard methods of solving linear equations can be used to obtain the solution.; input: What is the difference between -2 and 251860?
output: arithmetic
explanation: This is a simple subtraction questions, thus it belongs to the 'arithmetic' category. The answer obtained is yet another integer.; input: How many millilitres are there in 3/8 of a litre?
output: measurement
explanation: Conversion questions are 'measurement' questions. These involve converting a quantity from one unit to another.; input: What is the LCM of when 7, 11 and 13?
output: numbers
explanation: Number theory questions, especially those like finding remainders, GCD, LCM belong to the 'numbers' category. These questions typically involve factors, divisors, prime numbers etc.; input: Calculate prob of picking 1 o, 1 g, and 1 q when three letters picked without replacement from goqyyyypg.
output: probability
explanation: The 'probability' category questions can be quite easy to spot as they will typically ask you to find the probability of a certain occurrence.

Negative examples:
input: Suppose 5*f - 15 = 2*f. Solve v = f*v for v.
output: probability
explanation: Questions of solving equations are 'algebra' questions and not from the 'probability' class. Most algebra questions will involve unknown variables and perhaps multiple equations.; input: What is 0.4 plus 0.455?
output: measurement
explanation: This is a simple 'arithmetic' question incorrectly categorized as a 'measurement' question.; input: How many seconds are there in 6275.9 hours?
output: arithmetic
explanation: This conversion questions belongs to the 'measurement' category. Arithmetic questions will usually only involve basic math operations.; input: What is 0.4 plus 0.455?
output: measurement
explanation: This is a simple 'arithmetic' question incorrectly categorized as a 'measurement' question. Measurement questions typically involve converting a quantity from one unit to another.; input: Two letters picked without replacement from azzz. What is prob of picking 2 z?
output: numbers
explanation: This is a 'probability' question, not a 'numbers' question. It is clear because the questions in this category will always ask you to calculate the probability of some occurence.
