The main element that distinguishes an algebraic free response question from a normal Tex question is the format of the solution. First, the type of the answer is a "global free."
/* global free ans1 */
When writing out the solution, you will need quotation marks surrounding your equation. You also have the option to concatenate different parts of an equation as you would an group of String values (as shown in the example below).
To answer this type of question, students will be given an input screen similar to a scientific calculator. Unlike a short answer question these questions don't require submissions to match the answer in the system verbatim but rather the answer has to be mathematically equivalent to the correct answer on record (eg. X+1 is the same thing as 1+X). These questions are also not case sensitive. By nature though the answer has to be exact, π is not the same as 3.14.
