Example: To calculate 15 + 7:

1. Druk 1 5
2. Druk +
3. Druk 7
4. Druk = (Result: 22)

3.2 Direct Algebraic Logic (D.A.L.)

The D.A.L. system allows you to input equations exactly as they are written. For example, to calculate sin(30):

1. Ensure the calculator is in DEG (degrees) mode. (Press MODUS then select DEG if needed).
2. Druk sonde
3. Druk 3 0
4. Druk = (Result: 0.5)

3.3 Funksietoetse

Many keys have secondary functions, accessed by pressing the 2nd 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. Druk x² (Result: 25)

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

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

3.4 Geheuefunksies

The calculator includes memory functions to store and recall values.

• STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
• RCL: Recalls a value from a memory variable.
• M+: Adds the displayed value to the independent memory.
• M-CLR: Clears the independent memory.
