Many keys in this calculator serves one than one function which can be access through by pressing either "2nd"(Blue Key) or "ALPHA"(GREEN KEY). Such extra functions are noted on keys in Green or Blue color. These additional functions are accessed by first pressing corresponding color key and desired function Key.

For example:
pressing UP and DOWN keys navigates the screen up and down
if we press ALPHA key and then UP/DOWN key, it will scroll screen UP/DOWN by a page. Also you can use this combination for copy functions.
if we press 2nd Key instead of ALPHA, we can change Contrast of The screen

Just press the ALPHA key, followed by F1. Then you can use the TABs that are dispayed Beware there is no menu corresponding to the GRAPH key. Thus you can use ALPHA-F1, ALPHA-F2, ..., ALPHA F4.

On TI-84 plus calculator i know how do do fractions but i dont not know how to change the settings so when i type it in it actually looks like a fraction


I will assume that your calculator is equipped with one of the later Operationg systems. (2.53 MP and later).
To be able to use the Math Print templates you must set the IO display to MATH.
To do so turn calculator ON, press the MODE key to display the configuration pages. Scroll down to reach Page 2. At the top of the page you have Math and Classic. Use left arrow key to highlight MATH and press ENTER to validate.
Afterwards, when you want to type in a fraction or a loagb function, etc. press the ALPHA key. You will see TABS at the bottom of the screen. Activate a TAB by pressing the Fx key that is below it (F1, F2, or F3). You can move from one TAB to the next by pressing the Left/Right navigational keys.

Assuming that you pressed the improper fraction key, you will see a template of a stacked fraction. Enter the numerator in the upper square and the denominator in the lower square. Press the enter key.
In the MODE configuration you can force the display to be mixed fraction or improper fraction. You can also force a decimal representation of fractions (as results of calculations).

With the newer OS versions 2.53 MP and following you can manipulate fraction more easily. If your calculator MODE is set to MathPrint, you can use the [Alpha][Function keys] to access some functionalities
