Formula Question Source
HTML + LaTeX with {a} {b} {c} {d} and {=expr}
Rendered Preview
a=2, b=3, c=4, d=5
Paste a Formula question on the left to see the live solution preview.
Paste a Moodle Formula-type question script. The right pane shows the rendered solution with {a}, {b}, {c}, {d} substituted and every {=expression} computed live, just like the Moodle Formulas plugin would on a real attempt.
{a}, {b}, {c}, {d} → replaced with the values from the bar above.
{=expression} → evaluates the expression after variable substitution. Supports + - * / ** % and parentheses. Example: {=({a})**2+({b})} with a=2, b=3 becomes 7.
Works the same way Moodle’s Formulas plugin processes a question on a student attempt.
