Intuitive Fraction & Decimal Handling
Maintain perfect precision in your calculations. Easily input fractions with the `n/d` key (`/`) and convert results between fraction and decimal form with a single press of the `F◄►D` button. This is crucial for students in algebra and professionals in fields like chemistry or cooking where exact ratios are essential.
A Quick Start Guide to the TI-30XS
1. Perform Basic & Scientific Calculations
Type your expression as you would naturally write it on paper, like (5+3)*2. The calculator automatically respects the order of operations (PEMDAS/BODMAS). Use function keys for operations like sin(, making sure to close the parentheses. Press 'enter' to solve.
2. Access Secondary Functions (2nd)
Need a square root? Press the green 2nd key—notice the on-screen indicator and the key itself light up yellow. Now, press the x² key to activate its secondary command, sqrt(. This method applies to all keys with green text above them.
3. Toggle Angle Modes (DEG/RAD/GRAD)
Your trigonometric results depend on the correct angle mode. Press the `mode` key to cycle through Degrees (`DEG`), Radians (`RAD`), and Gradians (`GRAD`). The current mode is always shown on the display, ensuring you avoid common errors in your calculations.
