3.1 Osnovni izračuni

To perform basic arithmetic operations, simply input the numbers and operators in sequence. Press = da dobim rezultat.

• Dodatek: [Number] + [Number] =
• odštevanje: [Number] - [Number] =
• Množenje: [Number] × [Number] =
• Oddelek: [Number] ÷ [Number] =

3.2. Znanstvene funkcije

The calculator supports 240 scientific functions. Many functions are accessed by pressing the SHIFT key before the desired function key (indicated by text above the key).

• Trigonometrične funkcije: Uporaba greh, cos, porjavelost. For inverse functions, press SHIFT then the respective key (e.g., SHIFT + greh for sin^-1).
• Logaritemske funkcije: Uporaba dnevnik (osnova 10) in ln (naravni logaritem).
• Moči in korenine: Uporaba x², x³, √ (square root). For other roots or powers, use SHIFT with relevant keys.
• Kotne enote: Pritisnite NAČIN multiple times to cycle through angle units (Degrees, Radians, Gradians).

3.3. Memory Calculations

The calculator includes 9 variable memories (A-F, X, Y, M) for storing and recalling values.

• Trgovina: Input a value, then press STO followed by the desired memory key (e.g., A).
• Odpoklic: Pritisnite RCL followed by the desired memory key to recall the stored value.
• Memory Plus/Minus: Uporaba M+ to add the displayed value to memory M, and SHIFT + M+ (M-) to subtract.

3.4. Statistical Calculations

Za vstop v statistični način pritisnite NAČIN and select the STAT option. Follow the on-screen prompts to input data and perform calculations such as standard deviation and regression analysis.

3.5. Prilagoditev svetlosti zaslona

The calculator features a brightness adjustment function to optimize visibility in different lighting conditions and reduce eye strain.
