The goal of 4 Plus 4 is to learn math with fun.
It contains the three main sections "learn", "images" and "games". The app is free of ads and collects no data.

The "learn" section has a lot of different math topics. For each top exists an explanation and you can compute exercises for practicing.

In the "image" section you can reveal images by solving exercises of your preferred topics. Each image belongs to a theme like Dinosaurs, Planets or Jungle animals.
For each image the app provides some additional facts and information.

By solving exercises in the previous sections you can collect coins for playing mini games in the "games" section.

We constantly improve the app and working on new content. Feedback is always welcome and will be considered.
