3. Ntuziaka ọrụ
3.1 Basic Calculations
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = to get the result.
Example: To calculate 15 + 7:
- Pịa 1 5
- Pịa +
- Pịa 7
- Pịa = (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):
- Ensure the calculator is in DEG (degrees) mode. (Press MODE then select DEG if needed).
- Pịa mmehie
- Pịa 3 0
- Pịa = (Result: 0.5)
3.3 igodo ọrụ
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):
- Enter the number, e.g., 5
- Pịa x² (Result: 25)
Example: To calculate √x (square root of a number):
- Pịa √
- Enter the number, e.g., 2 5
- Pịa = (Result: 5)
3.4 Ọrụ Ebe Nchekwa
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.
