Math widget for iBook on Arithmetics

Nice Oak created a pretty cool interactive widget that was used in an enhanced ebook called “Arithmetic Made Understandable”, authored by John L. Hank, a retired math teacher. The ebook is available as a free download on the Apple iBookstore:

“I must also give enormous credit to Stephen Beauchesne who single handedly created the arithmetic interactive widget(s) that appear uniquely here for the first time,” said Mr. Hank in the iBook’s dedication section.

This will be the first of many widgets added to the iBook as new versions of the publication are made available.
