Math

Useful

So far, I have only found a handful of (in my opinion) useful websites where you can refresh and/or expand your math skills:

In English:

• Math Academy

In German:

• Mathematik Alpha
• OMB+

In my opinion, these three websites are particularly suitable for parents who want to take on a large part of their children’s home schooling.

Textbooks

The works of Friedrich Barth and his co-authors¹ are listed below.

Professor Dr. Bernhard Krötz and Mr. Barth have worked tirelessly to obtain the rights to make these books available to the general public. We would like to take this opportunity to express our sincere thanks to them!

The content covers all areas of high school mathematics from grades 7-13.

• Prof. Dr. Bernhard Krötz’s website
• Mathematik alpha website
