Numerus is a sophisticated scientific calculator designed especially for iPhone and iPod touch. It allowes 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 or correct them - just with a tap of your finger. You can also save any results into 26 variables (a - z) for later use.
