How to Use the Four Function Calculator

The Four Function Calculator is a simple tool designed to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. Follow this guide to understand how to effectively use the calculator to perform calculations.

Step-by-Step Instructions

Step 1: Enter the First Number

First Number: Start by entering a value in the “First Number” input field. This field is labeled “First Number” and requires a numerical input. It is mandatory to fill this field before proceeding further. You can input any number, including decimal numbers, as there is a step validation set to ‘any’, which allows for flexibility.

Step 2: Choose the Operation

Operation: Next, select the arithmetic operation you wish to perform. The calculator provides a dropdown list labeled “Operation,” where you can choose from the following options:

  • Addition (+): Choose this to add the two numbers.
  • Subtraction (-): Choose this to subtract the second number from the first.
  • Multiplication (×): Choose this to multiply the two numbers.
  • Division (÷): Choose this to divide the first number by the second.

It is important to select one of these operations as this field is required.

Step 3: Enter the Second Number

Second Number: Proceed by entering a value in the “Second Number” input field. This input is labeled “Second Number” and, similar to the first number, requires a numerical input. You can also input decimal numbers thanks to the step validation, which is set to ‘any’. This field is also required to be filled before moving forward.

Step 4: View the Result

Result: Once you have provided both the numbers and selected an operation, the calculator will automatically compute the result. The result is displayed in the “Result” field. This field is labeled “Result” and uses the selected operation to compute the result based on the inputs provided. The result will be formatted as a number, rounded to four decimal places to ensure precision in decimal calculations.

This simple step-by-step process allows you to perform basic arithmetic operations quickly and efficiently using the Four Function Calculator.
