### 2/5 — Boring but it works

*2012-04-06*

Not a bad teaching tool - but wicked boring!!  Where are the bells and whistles, or score keeping or SOMETHING...?!!

Should be free app - NOT worth paying for...

### 5/5 — Another addition tool

*2016-03-03*

This uses a different method to standard column addition - and you can practice that using this developer's 'C Addition' app.  But this 'partial' method is equally valid, and my nine year old daughter took to it straight away.
