Numerus is a sophisticated scientific calculator designed especially for iPhone and iPod touch. 

It allows you to enter an expression the way as you would write it on a paper.

Just like a tape calculator Numerus preserves your calculating history. Simply scroll back to previous results or entries to reuse them - just with a single tap of your finger.

You can also save any results into 26 variables (A-Z) for later use.
