Checking for Middle School, High School and University Level Math

Whether you are a middle school, high school or university level student, or an adult refreshing your memory, 4f Checker helps you to check if your 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.

Trust yourself

In math, there are many ways to get to a solution. Math operations can be made in different order, calculations in several or few steps. We all think in different ways, and it may be difficult to see it the way your teacher does and teaches you. This doesn't mean that your way is wrong. With the checker you can solve assignments your way, and check if it is mathematically correct.
