### 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.

### Learn how 4f Checker can help you in your class

Students in your class can use 4f Checker to find errors in their own solution. It gives them immediate feedback while they are working on the problem. This can be minor calculation errors, formulas and theories used in the wrong way, or simply writing the wrong numbers. They get help with locating the problem, and will be able to correct some of the errors themselves, while everything is still fresh in their mind. They can send their solutions to you and you can then help them with the more substantial problems, the issues they have not understood. This will remove the obstacles to learning, and your students are ready to learn new things. You can also use 4f Checker to find errors in your students' solutions, or to check your own model solutions.
