- Kuasa dan Akar: x², √x, yˣ.
- Factorials: n! (sering diakses melalui ke-2 fungsi).
Fungsi Memori
Store and recall numbers using the memory keys:
- STO: Store a number into memory.
- RCL: Recall a number from memory.
- JUMLAH: Add a number to the current memory value.
- EXC: Exchange the display value with the memory value.
Ciri Pengaturcaraan
The TI-55 III offers basic programming capabilities, allowing users to store and execute sequences of keystrokes for repetitive calculations. Consult the detailed guide book for instructions on creating, editing, and running programs.
Penyelenggaraan dan Penjagaan

- Gantikan bateri lama atau habis dengan yang baru.
- Memastikan HIDUP/MATI button is pressed firmly.
- Blank or dim display:
- Gantikan bateri.
- Ensure the calculator is not exposed to extreme cold, which can affect LCD performance.
- Keputusan pengiraan yang salah:
- Verify input values and operation sequence.
- Check the current angle mode (DEG, RAD, GRAD) for trigonometric functions.
- Clear all memory and previous calculations using the appropriate clear function.
- Kekunci tidak responsif:
- Clean the calculator surface around the keys.
- Replace batteries, as low power can sometimes affect key responsiveness.
