Maths Solutions

Maths formulae reference and equation calculator providing worked solutions.

Maths Solutions is available on the Android Market and for iPhone/iPod Touch and iPads on the Apple App Store.

Maths Solutions is an educational app aimed primarily at 2nd level mathematics students while also covering a number of 3rd level topics.

The app functions as both a reference containing a large collection of useful formula and as a formula calculator for computing fully worked solutions to common exam questions.
