Simple Calculator

How Does the Simple Calculator Work?

The simple calculator is used to perform all four arithmetic operations: addition, subtraction, multiplication, and division. First, choose the operation you would like to perform and fill out the input fields accordingly. Take one step at a time.

Why Use the Simple Calculator?

The simple calculator is a versatile tool suitable for various tasks such as math homework, taxes, or construction projects. Despite its simplicity, it can handle both simple and complex calculations efficiently.

A Brief History of Calculators

During the Renaissance period, in 1623, German professor Wilhelm Schickard invented the first mechanical calculator. French mathematician and physicist Blaise Pascal later invented a similar calculator in 1642, aimed at performing all four arithmetic operations with minimal human intervention. Today, digital calculators automate calculations without requiring significant human intervention.

Input Fields Explained

• Addition (+): Used to find the sum of two numbers.
• Subtraction (-): Finds the difference between two numbers.
• Multiplication (x): Provides the product of two numbers.
• Division (/): Solves for the quotient of two numbers.

Understanding the Results

Here's an example for each type of calculation:

• Addition: 2 + 2 = 4
• Subtraction: 4 - 2 = 2
• Multiplication: 2 x 2 = 4
• Division: 6 / 2 = 3
