Fractions are a basic function of mathematics. A fraction compares the relationship between parts and whole. The fraction one-fourth denotes that one part out of four is present. Inputting fractions into a TI-84 Plus graphing calculator requires extra attention due to the order of operations. However, once you get the hang of it, doing fractions on the TI-84 Plus is quite simple.
Instructions
1. Consider the mathematical function of the fraction. You must understand the nature of the math problem to input it into the calculator.
2. Turn on your TI-84. Your calculator should open with a blank screen. If not, hit the "Clear" button until your calculator shows a blank screen.
3. Enter the math problem in the calculator exactly as it is given to you. When you get to a fraction, place an open parenthesis before the first number in the fraction. Continue to enter the remainder of the fraction value and then place a closed parenthesis after the last number in the fraction. For example, "2 + 3/4" should be entered as "2+(3/4)."
4. Solve the problem by pressing the "Enter" key on the lower right-side of the keyboard.
5. Convert your solution back into a fraction by pressing the "Math" key and then selecting "1".
