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 MODD then select DEG if needed).
2. Gwasgwch pechod
3. Gwasgwch 3 0
4. Gwasgwch = (Result: 0.5)

3.3 Allwedd Swyddogaeth

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

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

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