This is a relatively simple and easy-to-use binomial expander for the iPhone, that does NOT need an internet connection to work! The app takes in an (x + y)^n (where n is a positive number, and x and y are any string or variable with a coefficient, such as 'x' or '3a') equation and expands it using the Binomial theorem.

Great for both Mathematics/Engineering/Sciences students and teachers alike.

(See http://en.wikipedia.org/wiki/Binomial_theorem for more information regarding the Binomial Theorem.)

What's New in Version 2.1

This long-awaited update contains the following:

- A completely revamped expansion algorithm. The app can now detect coefficients attached to typed variables and are then multiplied into the final result. In other words, the brackets mess is completely gone!
- Support for the iPhone 5's taller screen
- Other minor bugfixes and improvements

Thank-you to all who have purchased the app so far and also to those who have sent in your feedback. I apologise for the delay in addressing some of your concerns but please do keep sending your feedback to binomial@wakachamo.com, and I will do my absolute best to make sure that this tiny, but useful app is perfect for your needs, be it at work or during study time.

Thanks again :) -Joaquim
