About this app

The `i-Computer` is a calculator for algebraic expressions that includes basic mathematical functions (such as sqrt, exp, log, abs, sin, cos, tan, arctan, arccos, and arcsin), as well as the nth root and logarithms to any base. It also supports special numbers (e, π, φ, Φ) and standard mathematical operations. This makes it ideal for teaching mathematics—especially for beginners—as it features two main screens and two helper screens.

Screen-1(touch screen): It is interactive touch screen where you can syntax and correct the algebraic or arithmetic expression with the keyboard format. To modify or cancel the content, you can use the control buttons.

Screen-2(simulator screen): Here, the expression simulates the way someone writes by hand on paper in the classic Μathematical format. The calculated numerical value of the algebriac expression is also presented .

Screen-3 (Syntax Errors Screen): This screen displays syntax errors in real time as you type your expression. Tap on the screen to open a popup that lists all errors, their positions, and possible ways to fix the syntax errors.

Screen-4 (Definition Errors Screen): This screen displays invalid mathematical definitions that occur during the calculation of the expression. Refer to Screen-2 to see the type of error and the position where the caclculation of the algebraic expression stopped.
