# Check every step in the calculation, not just the answer

**eMathChecker **allows you to check if a derivation is mathematically correct. The checker formulates each step in the derivation as a mathematical theorem, and sends the theorem to an automatic theorem prover that runs in the cloud. The derivation is correct, if each step in the derivation is proved correct. The checker warns for each derivation step that it was not able to prove correct.
