You can try using latex instead.

In the algorithm section write

Then in the answer boxes put for example 

Here is the result.

@chrisb @mcla Thank you both for the math app files, these look good! Preferably I would want the option to draw both linear lines and hyperboles, so if you know of a way to do this let me know. For now, I will try to adjust these math apps a bit to fit my needs, but I am not that skilled yet at Mathapp, so if you have any tips, please let me know

@Pierre  I could not agree more, it would be fairly simple HTMl for them to allow the instructor to force, either Text Or Symbolic (in the same way one can force students with the Maple-Graded response type).

@Metahofzicht Nailed it. I found out how to fix it.

My grading code:

local I:=II:
if evalb(simplify(algsubs(I = a^4/(32*sqrt(3)), algsubs(C = 192, $RESPONSE) = $RV1))) then 1.0;
elif evalb(simplify(algsubs(I = a^4/(32*sqrt(3)), algsubs(C[1] = 192, $RESPONSE) = $RV1))) then 1.0;
elif algsubs($fact2 = 1,$RESPONSE) <> $RESPONSE then 1.0;
else 0.0;
end if;

Custom previewing code: local I:=`I `:printf(MathML[ExportPresentation]($RESPONSE));

my algoritm:

$fact2 = "E*a^4/L^3";
$RV1 = "$fact2*2*sqrt(3)";
$RVdisplay = "printf(MathML[ExportPresentation]($RV1))";
