\textbf{Formula Response} problems ask the student to type in a formula as an answer.
If the answer is $2x^{2}+4$, the student is allowed to type {}``2{*}x{*}x+4'',
{}``x{*}x + x{*}x + 4'', {}``2{*}x\textasciicircum{}2 + 14 - 10'', or
any other equivalent expression. Formula Response problems have many of the
same characteristics of Numerical Response problems, including the ability
to run scripts, dynamically generate answers, etc.
