You do the problem.
We check the work, not just the answer.

Type in your answer and get told exactly which step went wrong — not just a red X. Covers algebra through calculus, with problems that adjust to what you're actually getting wrong.

Trigonometry — right triangles
Find sin θ, given opposite = 3, hypotenuse = 5
Correct. sin θ is opposite over hypotenuse — you already had both values from the triangle, so this was a direct substitution: 3/5.

What's actually in the workbench

01

Every step shown

Wrong answers come back with the specific step that broke — not "incorrect, try again."

02

Difficulty that moves with you

Miss a few in a row and the next problems back off. String together correct answers and they get harder.

03

A formula sheet you can actually read

Every rule the workbench uses, laid out by topic, in the same notation you'll see in the problems.
