- Enter fractions using the [a b/c] key
- Convert between improper fractions and mixed numbers
- Perform arithmetic operations with fractions
- Simplify fractions automatically
Statistical Mode Operations
To perform statistical calculations:
- Press [MODE] and select “STAT” (3)
- Enter data points using [DATA] key
- Press [STATVAR] to view statistical results (mean, standard deviation, etc.)
- Use linear regression functions to find best-fit lines
Maintenance and Care
Proper care will extend the life of your TI-30XB:
- Store in a protective case when not in use
- Avoid exposure to extreme temperatures or moisture
- Clean the solar panel regularly with a soft, dry cloth
- Replace the backup battery (LR44) when the display becomes dim
- Avoid pressing multiple keys simultaneously to prevent key jamming
