4 Plus 4

Math often feels complicated. Not because it’s hard, but because it’s explained the wrong way. 4 Plus 4 is different.

No overloaded explanations, no distractions, and no shortcuts. Just clear tasks that guide you forward step by step.

The app is ad-free and does not collect personal data.

It is built around clear learning modules such as Number Basics, Advanced Numbers, Basic Arithmetic and Fractions Basics, where key mathematical concepts are practiced in a structured and easy-to-follow way. In additional sections, you can apply what you have learned in a playful and entertaining way.

4 Plus 4 combines clear learning with motivation, progress, and fun — ideal for getting started, refreshing knowledge, or practicing in between.

We continuously expand the app with new content to make learning mathematics as simple, understandable, and enjoyable as possible.
