Non Programmable Calculator

Step-by-Step Guide to Using the Basic Non-Programmable Calculator

This guide will walk you through the process of using the Basic Non-Programmable Calculator effectively. This tool allows you to perform various mathematical operations such as addition, subtraction, multiplication, division, power, and square root. Follow the steps below to carry out your calculations.

Step 1: Entering the First Number

• Locate the First Number Field: Find the input field labeled as “First Number”.
• Input the First Number: Click on the field and enter the numerical value. Ensure the number is within the range of -999,999,999 to 999,999,999, as the calculator supports numbers only within this range.
• Validation: This field is required, so ensure it is not left blank.

Step 2: Selecting the Operation

• Locate the Operation Dropdown: Find the dropdown menu labeled as “Operation”.
• Select the Desired Operation: Choose the mathematical operation you wish to perform from the available options:
  • Addition (+)
  • Subtraction (-)
  • Multiplication (×)
  • Division (÷)
  • Power (^)
  • Square Root (√)
• Validation: It is mandatory to select an operation to proceed.

Step 3: Entering the Second Number

• Locate the Second Number Field: Find the input field labeled as “Second Number”.
• Input the Second Number: Enter the second numerical value. Like the first number, ensure it falls within the accepted range of -999,999,999 to 999,999,999.
• Validation: This field is also required. However, for operations like Square Root, the second number might not be necessary; refer to instructions in subsequent steps.

Step 4: Running the Calculation

• Perform the Calculation: Once all the fields are correctly filled in and an operation is selected, the calculator will automatically compute the result.
• Special Cases:
  • For Division, ensure the second number is not zero, as dividing by zero is undefined.
  • For Square Root, only the first number is used, and it should be non-negative to produce a real number result.

Step 5: Viewing the Results

• Locate the Results Section: The calculator will display the result of the selected operation with a suitable label such as “Addition Result”, “Subtraction Result” etc.
• Understand the Output: The result is formatted to two decimal places for better readability. If an operation does not apply (e.g., square root with a negative number), the result might display as null.

Conclusion

By following these steps, you can effectively use the Basic Non-Programmable Calculator to perform a variety of numerical operations. Ensure all inputs meet the specified criteria and note the conditions associated with each mathematical operation to obtain accurate results.
