- Kekuatan dan Akar: Menggunakan [x²] untuk kotak, [√] for square roots, and [x^] untuk kekuatan lainnya.
Fungsi Ilmiah
- Fungsi Trigonometri: Menggunakan [dosa], [cos], [tan]. For inverse functions, press [MENGGESER] then the respective function key ([sin⁻¹], [cos⁻¹], [tan⁻¹]).
- Logaritma: Menggunakan [log] for base-10 logarithm and [ln] for natural logarithm.
- Satuan Sudut: To change between Degrees (DEG), Radians (RAD), and Gradians (GRAD), press [MENGGESER] Kemudian [TIDAK BISA] (SETUP), navigate to "Angle Unit", and select your desired unit.
- Konstanta: Access mathematical constants like [π] (SHIFT + x10^x).
Fungsi Memori
- Store Value: To store a value, input the value, press [STO] (SHIFT + RCL), then press the key corresponding to the desired variable (A, B, C, D, E, F, X, Y, M).
- Recall Value: Untuk memanggil kembali nilai yang disimpan, tekan [RCL], then the key corresponding to the variable.
Fitur Khusus

- Maths Box: This feature allows simulation of random experiments. Press [TOOLS], then select "Maths Box" to access coin toss or dice roll simulations.
- Statistics Mode: To perform statistical calculations, press [TIDAK BISA], then select "Statistics". Input your data and use the options to calculate sums, standard deviations, and perform regression analysis.
- Verifikasi Fungsi: Use the "Verify" function to check if an equation is true or false.
- Fungsi Tabel: Generate a table of values for one or two functions (f(x) and g(x)). Press [TIDAK BISA], then select "Table".
Pemeliharaan
Pembersihan
Untuk membersihkan kalkulator, lap dengan kain lembut dan kering. Untuk kotoran membandel, lap sedikit.ampen the cloth with water and a mild detergent, then wipe dry immediately. Do not use strong solvents, abrasive cleaners, or spray cleaners directly onto the calculator.
