What is Binary Multiplication? | Binary Multiplication Calculator

Binary multiplication is performed similarly to decimal multiplication but uses only two digits: 0 and 1. In binary, the multiplication of two bits follows these rules:

  • 0 * 0 = 0
  • 0 * 1 = 0
  • 1 * 0 = 0
  • 1 * 1 = 1

These rules form the basis of how binary numbers are multiplied together.

How to Use the Binary Multiplication Calculator

Steps to Perform Binary Multiplication

  1. Input the first binary number in the first field.
  2. Input the second binary number in the second field.
  3. Click the “Calculate” button.
  4. The result will be displayed in binary form.

Using this calculator simplifies tedious multiplication, making it faster and more efficient.

Example of Binary Multiplication

Example 1: Multiply 101 (5 in decimal) and 11 (3 in decimal)

Let’s walk through the multiplication:

    • 101
    • x 11
101(first row)
101(shifted left)
  • Add the results which gives us 1111 (15 in decimal).

Thus, the binary multiplication of 101 and 11 equals 1111.

Example 2: Multiply 1101 (13 in decimal) and 101 (5 in decimal)

Follow these steps:

    • 1101
    • x 101
1101(first row)
0000(shifted left)
1101(shifted left again)
  • Add the results, which gives us 10011101 (65 in decimal).

Thus, the binary multiplication of 1101 and 101 equals 10011101.
