Ti 84 Programming is a kind of small computer, actually calculator on graphics production, for calculations, math actions, strings, list of numbers and single numbers, based in Texas and there's a most useful and easy calculators based industry. It's actually a program of language, easy to set and work, that proceeds to above actions upon some transactions on the screen. It's easy to deal and actually translates to the other language Program installed, the Assembly. This IT 84 Program is part of the whole calculators system TI Basic Programs, such as TI 89 Titanium, TI 92 Plus, this actually TI 84 programming, belongs to the Silver Edition general program of TI Basic Programming, and is more powerful, for it has a strong structure of command execution, and despite its low speed is preferred for its easiness, and many programs execution.

It works like this : You go to the Home screen and hit ‘'ENTER'', then this goes on to next and you type the name or number you want, then upon acceptance it becomes totally blank; then you press ‘'ENTER'', and there the result transaction is produced on whatever you want to calculate. And so on, it can be used as many times as you want with the equivalent transactions, translating to Assembly language, always, and the combination of both may produce wonderful results, in whatever combined actions you precede t. For example you may combine numbers with numbers, names with names or names with numbers. Then the output is according to user's input. One thing we should mention is that it works just only with files, downloading the appropriate file in order to continue requires another transaction to continue, and upon typing a data, these functions in a multiplication way, and so one.

Then in order to continue, you press the ‘'PGRM'' button, to recall the appropriate program for the transaction, and also store it. Then you press the Quit button, for the screen to become blank again, and then the ‘'Exit'' one to exit. The data typing as well as transfer involves, some variables, the system works with variables, and there's also the variable button, for modifying the transaction, or giving it another variable, change the result. The whole IT 84 Programming system being variant as said above, works only with variables. All files are called variables, and there's a separate variable for each file, also to each data typed corresponds to one variable, and rules of transaction should be followed strictly, as its function is formula based, as self-understood. The variables have a storing and recalling capacity, based on recall of files, with specific transaction, and the key of recall is the variable itself.

Procedure is simple, and can be followed by anyone with elementary knowledge of calculators. It's this way like the actions of Excel we all know, I think knowing Excel, you may easily use TI 84 Programming, and all the variant relative programs of is, as above, but also the vice versa. It is ideal for small business, for personal accounting services, but also for expansion of knowledge and why not, for fun. You have always something new to learn out of such a tool, also have a good time, passing your time at the same time.
