Smart Calculator is a great tool for anyone needing mathematical help with calculations. The program displays a symbol representing your current operation at the left of the entry field and also shows big numbers in natural style, not as 12345E+1234. This is the only calculator program that graphically shows that it ties directly to the numeric keypad. Choose between options like colors, fonts and language you want the calculator program to be in. An in-depth help section is available which can explain how to use the functions, what buttons do, and much more. This is a wonderful calculator with many different features.
