DESCRIPTION OF THIS NON-GRAPHIC FREE VERSION:

Use the scientific calculator look-alike touch keyboard to enter expressions and functions, all on one screen without "2nd" key.

SYNTAX HIGHLIGHTING INCREASES READABILITY

When you enter expressions they are displayed with colored text; the negative sign has a different color than the subtraction sign, the scientific notation 'E' is highlighted by color so you don't miss it. During the input of an expression matching parentheses are highlighted with color to make multi parentheses input more readable.

EASY HUMAN READABLE ERROR MESSAGES

In case you enter an illegal expression you will get an easy-to-read error message. Also, if a calculation error occur a specific human-friendly error message will tell you what went wrong; 'Division by zero', 'Log of a negative number is illegal' etc. Graphoid is made to help us avoid mistakes!

STORED VARIABLES AND EXPRESSIONS

You can easily store variables with an arbitrary name and use them in future calculations. The last entered expressions are automatically stored and can be reused or edited.
