If you need to quickly reference important notes, it can sometimes take too long to look through a book to find the notes you need. Using the TI-83 calculator, you can store a set of notes in the calculator's program function. Under the program function, you can type any notes you want using words. This is particularly helpful for keeping notes such as formulas. It is also handy because the TI-83 calculator is smaller than most books, so it helps you reduce the amount of items you need to carry.
