2. Presse 2e F, alors péché (which is the primary function of the key).
3. Entrer 3, 0, puis appuyez sur =L'écran affichera 0.5.

ÉcrireView Afficher

L'écritView feature allows you to input and display equations in a natural, textbook-like format.

• Enter equations as they appear in your textbook. The calculator will display fractions, roots, and other expressions clearly.
• Use the arrow keys (left, right, up, down) to navigate within an equation for editing.

Display Modes (DEG, RAD, GRAD)

The calculator supports three angle modes: Degrees (DEG), Radians (RAD), and Gradians (DIPLÔMÉ).

• Pour changer de mode, appuyez sur MODE key repeatedly until the desired mode (DEG, RAD, ou DIPLÔMÉ) is highlighted or selected.
• The current angle mode is indicated on the display.

Fonctions de mémoire

La calculatrice comprend des fonctions de mémoire permettant de stocker et de rappeler des valeurs.

• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Memory Minus): Subtracts the displayed value from the independent memory.
• RCL (Recall Memory): Recalls the value stored in the independent memory.
• STO (Store Memory): Stores the displayed value into a specific variable memory (A, B, C, D, E, F, X, Y, M).

Fractions and Decimals

• To enter a fraction, use the un b/c clé.
• To convert a fraction to a decimal or vice versa, press the 2e F touche suivie de la un b/c clé.

Statistical Functions

The calculator includes various statistical functions.

• Pour entrer STAT mode, appuyez sur le MODE touche jusqu'à STAT est sélectionné.
• Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.
• Refer to the detailed function guide for specific statistical operations.

Entretien

Un entretien approprié garantit la longévité et les performances optimales de votre calculatrice.

Nettoyage
