CALC is really clever.
CALC does live math expressions: From simplifying even the simplest like "1+ -2", that you can type the same way you'd on a paper (without the need for "negating" a number afterwards) ... to more advanced expressions like "1/3 + -( 3 x 9(log(4;8) + sind(90)))" where you can even specify a base for the log() function, use natural input without the need to insert a multiplication symbol or worry if you did the trig. function "sinus" in RAD or DEG, or closed all parentheses.

Advanced calculator.
By swiping left and right on CALC, you can easily access over 60 advanced math functions, constants and symbols + create limitless number of your own!

History log.
CALC remembers what you have calculated. Swipe up, and you can see all your previous calculations and perform aggregate functions.

Built in converter.
