The TI-83 Plus includes dozens of options to help solve or display many types of math problems, such as square roots, matrices and absolute values. The calculator also has you covered if an answer must be displayed as a fraction. There is not, however, a dedicated "Fraction" button located on one of the calculator's dozens of buttons. In order to convert a number to a fraction, you must navigate the TI-83 Plus's built-in menus.
