About Binary Calculator

What Is a Binary Calculator?

This tool performs arithmetic — addition, subtraction, multiplication, and division — directly on binary numbers, useful for students learning binary math or developers who want to verify a calculation without converting to decimal first.

How to Use the Binary Calculator

  • Enter your two binary numbers
  • Choose the operation
  • Click Calculate
  • Review the binary result

Key Features

  • Supports all four basic operations
  • Works directly in binary — no manual decimal conversion needed

Who Uses This Tool

Students learning binary arithmetic and checking their work. Developers doing a quick binary math verification.

Frequently Asked Questions

Does it show the decimal equivalent too?
The primary result is in binary; you can cross-check against a binary-to-decimal converter if you need the decimal value as well.

Is this tool free?
Yes, using the binary calculator is completely free.

Frequently Asked Questions

What do AND, OR, XOR actually do?
These bitwise operators compare numbers bit by bit. AND returns 1 only where both bits are 1, OR returns 1 where either bit is 1, and XOR returns 1 only where the bits differ.
What does left shift and right shift do?
A left shift moves all bits left (multiplying by 2 per shift), while a right shift moves bits right (dividing by 2 per shift, rounding toward zero).
Why does NOT only need one number?
NOT is a unary operator — it flips every bit of a single number (0s become 1s and vice versa), so the second number field isn't used for this operation.
Is this tool free to use?
Yes, using the binary calculator is completely free, with no signup or usage limit.
