FAQ and problem solver for the Ti-84 Plus (CE)
Tips, hints, and recommendations if you have problems with your Ti84
The Ti-84 Basic programs of this website are sometimes very extensive and require sometimes a lot of memory space. If problems occur, you can usually solve them with the recommendations on this page.
Before you install a program, you must unzip it if you have downloaded the program from the website. Programs work on both the Ti-84 plus CE, and the Ti-84 plus (silver edition). It should be noted that the Ti-84 plus CE is 2 times faster than the Ti-84 plus and has more memory space available.
For each program, it is recommended to try the examples on the website first to get used to the programs.
