Basically, you go to the PRGM button on your calculator, scroll over to NEW, and hit enter. Then you name it whatever you want. hitting the PRGM button allows you to access many tools. If, Then, Else, Goto, and Lbl allow you to make if-then statements. you do that like this
:If (this is an example) X=3
:Then
:Goto 9
:Else
:Goto 0
Then you have to make Labels 9 and 0, and have them do something. End and stop both end the program, but sometimes one works and the other deosn't. Pause halts the Program until the Enter button is pushed, but there are ways to create time delays. One way is to have a loop
:0->x
:Lbl 0
:X+1->X
:If X<15
:Then
:Goto 0
:Else goto 1
:Lbl 9
:whatever you want it to do now
The Menu button is one of the hardest things to work with, but one of the most helpful. You need a lot of labels typically. A sample menu is shown here.
:Menu("Title","Option 1",1,"Option 2",2,"Option 3",3)
then you have
:Lbl 1 that is for your first option, and so forth.
prgm is used if you want to run a program inside one of your programs.
Input is used to get a number as in
:Input X
it will display when you run it as a ? and the number you type will be saved to that variable.
Prompt is the same thing except that it will display as
X?
Disp is one of the most important tools you will find on your calculator.
Disp jklo will display the product of j times k times l times o
Disp "HI will display HI
Output is used as
:Output(1,1,"HI MY NAME IS JOE
the 1,1, is necessary, and is the position on the screen
:Output(2,1,"HI MY NAME IS JOE
will display
HI MY NAME IS JOE
ClrHome clears the home screen, and must be done before any output
GetCalc and Send( are used in 2-calculator programs, almost always games, and are self-explanitory
EXEC only does another program within yourself
If you can't get out of anything, hit the 2nd off button, and it will turn off or display ERROR:BREAK
1:Quit
2:Goto
beware of loops such as
Lbl 9
blah blah blah
Goto 9
or
in the program HI
Prgm HI

Is a TI83 required for college?
No, it really depends on the college. Some colleges don't allow any calculators for their math classes. Everything that can be done on a TI83 can be done with the human brain, so some professors make tests with easier computations so that you don't have to use a TI83
How do you put a colon on ti83?
Press "ALPHA", then press "."

Batteries on ti83?
The TI-83 calculator uses 4 AAA batteries.
Can you replace the TI83 with a cheaper calculator in High School math classes?
It will depend on the class. Nothing is impossible without the TI83, but some classes might require it so you can graph and write programs to go along with the math curriculum.
How do you make a TI83 calculate wrong?
You cannot. A calculator is programmed. It is made to calculate correctly.

Where can you download a free online TI-84 calculator?
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
