A simple calculator is a fundamental digital device designed for performing basic arithmetic operations. It is an essential tool for performing calculations involving addition, subtraction, multiplication, and division. Simple calculators are commonly found on various electronic devices such as computers, smartphones, and dedicated handheld devices.

The primary purpose of a simple calculator is to assist users in solving everyday mathematical problems quickly and accurately. It typically consists of a numeric keypad, a display screen, and basic mathematical function buttons.

Simple calculators are user-friendly and intuitive, making them accessible to people of all ages and mathematical backgrounds.

The core features of a simple calculator include:

Addition: Adding two or more numbers together.
Subtraction: Finding the difference between two numbers.
Multiplication: Calculating the product of two or more numbers.
Division: Determining the quotient of one number divided by another.
Clearing: Removing the entered numbers or results to start a new calculation.
Some simple calculators may offer additional features such as memory functions (storing and recalling numbers), percentage calculations, and a square root function. Despite their simplicity, these calculators are invaluable tools in a wide range of everyday scenarios, from shopping to budgeting to basic mathematical learning.

Scientific Calculator:
