• MODE: Changes the calculator's mode (e.g., COMP, STAT, EQN). Press MODE repeatedly to cycle through options.
• CLR: Clears specific data or settings. Press MAJÚS aleshores CLR to access clear options.
• DEL: Deletes the character at the cursor position.
• AC: Clears all input and returns to the initial state.

Funcions avançades

The 82Ms-A supports 240 functions, including trigonometric (sin, cos, tan), logarithmic (log, ln), power (x², x³), roots (√, ³√), fractions (a b/c), and statistical calculations. Refer to the specific key labels and their SHIFT/ALPHA functions for detailed usage.

• Funcions trigonomètriques: Ús pecat, cos, bronzejat keys. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), use MAJÚS with these keys.
• Logarithmic Functions: Ús registre (base 10) i ln (natural logarithm) keys.
• Power and Root Functions: Ús x² per al quadrat, MAJÚS aleshores x² for square root (√). For other powers and roots, use x³ or MAJÚS aleshores x³ (³√).
