This program is design for tablets and phone devises! Math in One graphing calculator can evaluate any mathematical expression of any length and complexity that includes real or complex numbers. It can operate in decimal or common fractions format. It graphs in Cartesian, polar coordinates or parametric equations. Expressions can be entered in editor text box Input Output Display (IOD) and then edited in the middle of the string (text) on any line. The calculation execution can be performed from any line in (IOD). If a user makes an unsupported entry during the operation of this software, the calculator will generate an error message and explanation. The help is built in to the calculator and available on line. It also includes a uniquely designed Unit Converter, Financial Analysis (savings, loans, bonds) and can save Graphs, Memory, Expressions and IOD in to a File. In Cartesian coordinates, plotted multiple graphs can be moved and resized. Function values may be displayed for a specific independent variable. Tracing the pointers on a screen, one can find zeros, minimums, maximums and intersections of functions. Function
