Many keys have secondary functions, accessed by pressing the 2yèm F key first. The secondary functions are typically printed above the primary key function.

Example: To calculate x² (square of a number):

1. Enter the number, e.g., 5
2. Peze x² (Result: 25)

Example: To calculate √x (square root of a number):

1. Peze √
2. Enter the number, e.g., 2 5
3. Peze = (Result: 5)

3.4 Fonksyon Memwa

The calculator includes memory functions to store and recall values.
