This program is meant to transform your TI into a useful calculator. The functions provided are basic addition, subtraction, multiplication and division. Although these tasks tend to be executed relatively slowly on the unexpanded TI, they are performed considerably faster when the program is run in Extended Basic. If a printer is attached then a copy of your calculations may be obtained.

Each number in your calculation is entered separately followed by the sign for the function to be performed. Both of these are kept in memory should either need to be corrected. If an input error has been made this may be corrected at any stage and the entire calculation is automatically changed.

Although there is no fault with the design or running of the program, I can't really see the program being of great value to the average user. Unless you need to make regular long and complicated calculations then it's hardly a worthwhile investment. In the time taken to load and run the program then enter the numbers you could have checked and re-checked answers obtained from a calculator or even your own brain power.
