If you don't wrap the string in the latex function, it's displayed as plain text: $\\var{expression}$

\n

The correct way to do it is as follows: $\\var{latex(expression)}$

\n

$\\var{latex(join(split(\"123 123\",\" \"),\"\\\\ \"))}$

\n

$\\var{latex(tryThis)}$ vs $\\simplify{{latex('\\frac{3}{2}')}}$

\n

$\\simplify{{latex(tryThis)}}$ !!

\n

$\\simplify{4*{expression('x')}}$  --- is this how to get random variables?!

\n

\n

$\\var{latex('\\frac{1}{2}')}$

\n

\n

$\\var{test}$ $\\var{blah}$

\n

\n

{text} {math}

\n

{if(a=0,\"\\$\\\\frac\\{\\\\simplify\\{x^2-2x+12\\}\\}\\{x(\\\\simplify\\{x-\\{b\\}\\})(\\\\simplify\\{x-\\{c\\}\\})\\}\\$\",\"\\$\\\\simplify\\{(x^2-2x+12)\\/((x-\\{a\\})(x-\\{b\\})(x-\\{c\\}))\\}\\$\")}

{pro}

\n

{latex(pro)}

\n

$4\\var{pro}$

\n

$4\\var{latex(pro)}$

latex(pro)

$4\\var{lpro}$

$\\simplify{4{expression(pro)}}$

$\\var{epro}$
