Multiplication in Binary

Multiplication technique

Multiplication in binary has three basic operations:

• $1 \times 1 = 1$
• $1 \times 0 = 0$
• $0 \times 0 = 0$

The rest of the technique is to apply the decimal method of multiplication; i.e., to stack up the individual numbers and multiply digit by digit, adding up the final answers. Let’s see an illustration with a few examples.
