About Calculator

A calculator is a device that performs arithmetic operations on numbers. The simplest calculators can do only addition, subtraction, multiplication, and division.

Modern calculators are more sophisticated, capable of performing complex mathematical functions, storing results in memory, and even graphing equations.

Our online calculator provides both basic arithmetic operations and additional functions to help with everyday calculations, whether for work, school, or personal use.

  2. Clear Functions: Use 'C' to clear everything, 'CE' to clear the current entry.

  5. History: Use the "Show History" button to view your previous calculations.
