Mathematical Formulas|教育線上App不用買

The application contains well known and useful formulas of many different topics of mathematics. It is a great tool for (not only) students of grammar, high and university schools.

Please note that the app size is only 100 kB! The reason is that it contains NO IMAGES (except the launcher icon) and all formulas are rendered in run-time from text resources, using my own simple mathematical rendering engine. It also means that the application can be easily localized to any number of languages.

The formula text size can be increased or decreased and clicked to share in all ways your device supports (Facebook, email attachment, Google Drive etc.).

Enjoy! :-) And if you wish to add more formulas, please do not hesitate to contact me.

Explanation of permissions required by the application:

WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE: In order to share a formula on Facebook or attach it to an email, a PNG image file containing the selected formula must be created first and stored to the device. The files are very small and do not occupy any significant space.
