There's no shortage of math-related educational freeware (or, as they say in Britain and many other places, "maths") and U.K.-based Eptsoft would clearly like your local council to choose its product, Accounting Maths and Computing for Business Studies V10, for your schools.

The device in question is the HP 12c calculator, first launched exactly 30 years ago today, on September 1, 1981.
