As you progress into more advanced math courses, the TI‑83 graphing calculator—produced by Texas Instruments—becomes an indispensable tool. It handles basic arithmetic, plots complex graphs, and manages fractional operations with precision.

Step 1: Power On

Press the yellow button located just below the screen and above the arrow keys to turn the device on.

Step 2: Enter the Fraction Expression

Input the problem exactly as it appears. For example, to add 1/4 and 12/17, type (1/4)+(12/17). Use parentheses around each fraction and the divide symbol (the slanted line) to separate numerators from denominators.

Step 3: Compute

Press Enter and the result will display on the screen.

Following these steps ensures accurate fraction calculations on the TI‑83.
