Matrix Multiplication APK

1.1.0 for Android 2.2 and up and up

Andreas Modahl

Small app for practicing mental arithmetic and matrix multiplication.

Package name:

org.ajm.laforkids

If you want to improve your mental arithmetic while also practicing linear algebra then this app is for you.

This is not a calculator, the apps purpose is learning matrix multiplication and practicing mental arithmetic.


My own experience:
I use the app to compute just a few matrices a week, when I am in an elevator or waiting for the bus. It has improved the speed of my mental arithmetic a lot, I also think and reason about matrices and vectors much quicker than before.

Matrices are used everywhere, in engineering, computer science, mathematics, physics, biology, economics, statistics,... The most important operation associated with matrices may be matrix multiplication, and a good understanding and lots of practice with matrix multiplication is key to understanding many concepts in these fields.


This app is small and use little battery.
