Numeric questions use a numeral for a response rather than a multiple choice option.
Numeric answers can be submitted as an integer, decimal, or scientific notation without spaces. By default, a given answer will be scored as correct if it is within 1% of the correct answer. However, this value can be changed when editing the question. The Quest system will calculate answers to at least six digits. For most problems in Quest the system does not calculate based off significant figures.
Students can use scientific notation for very large or very small numbers. For example, you could write 468 as 4.68e+02.

There are two kinds, the very common Numeric Free Response (NFR, also called Open), and the Algebraic Free Response, which offers a pallet to select functions from.
Numeric Free Response (template #174705):
Notice that the answer (ans1= ) in the code box calls a global double variable that is the solution. Ex: ans1=@a1 (this is different when coding a TeX multiple choice answer, where ans1= the answer choice number that is correct; more info on that here.)
Algebraic Free Response (template #179792. Notice how variables are expected in the answer, in this case, 'mx+b')

Question tolerance
The answer tolerance for a question can be set in the right-hand box above the code portion of a TeX question. Only one tolerance can be set for the entire question and applies to all of the question's parts. For any numerical response, a student's submission may be within this tolerance range (+/-) and still be considered correct. The default tolerance for most numerical response questions is 1%. For instance, if a given question has an answer of 32.00 and a tolerance of 1%, a student's response could be between 31.68 and 32.32. A 1% tolerance can usually cover most student rounding errors.
