  the PDF User Manual     

4 iPad, this calculator has a unique Expression mode & the Algebraic computation mode, and dozens of mathematical functions. Scratchpad workflow; the scratchpad can evaluate equations without going to the calculator. Those who purchase the Scientific Expression calculator should keep their eyes open for the updates to come.

The Expression mode allows you to input an entire equation before evaluation, so you can be sure the equation is correct. This is a great advantage whether adding a series of numbers or solving a complex trigonometric equation.

The Algebraic mode is the standard mode on many calculators, familiar to most users. The paper tape saves as much output as you want, and can be hidden.

The scratchpad allows you to work on problems, create and store equations and notes. You can then select an equation, and have the equation evaluated in Expression mode without leaving the scratchpad.

The Scientific Expression calculator is a great calculator for students, engineers and scientists. Comments, questions and problems can be sent to "iOS@azarhi.com".
