The application "Symbols.1plus1" makes computation funny.
The application is organized like a math sheet. There is a matrix of cells and in each cell you can enter a symbol (a number or an operation).
The engine recognizes your input sign and converts it to a number. Using your inputs the application computes the formula you have entered.
The keyword in this equation is to write the symbol = at the end of your operations. This one is triggering the computing algorithm.
In this way the computing becomes more easy and the user has the option of viewing the entire operations.
Of course you can start with some basic operation like 1 + 1 =
But in short time you will want to compute more complex formulas. The application provides the functionality to compute complex algebra formula.
A good way to check the application features is to take a look at help which is written pretty straightforward, so the learning process will take only a few minutes.

Features:
- IOS 4.2 tested
- handwriting recognition. A couple of explanations here. The handwriting recognition is done with a custom algorithm.
What is making it different is the "forget" functionality, which speeds up the algorithm convergence to user specific handwriting.
- compute many formulas
- chain your calculations
