Binary multiplication uses the same technique as decimal multiplication. In fact, binary multiplication is much easier because each digit we multiply by is either zero or one. Consider the simple problem of multiplying 110_{2} by 10_{2}. We can use this problem to review some terminology and illustrate the rules for binary multiplication.

110 x 10 

110 x 10 000 

110 x 10 000 110 

110 x 10 000 110 1100 
When performing binary multiplication, remember the following rules:
 Copy the multiplicand when the multiplier digit is 1. Otherwise, write a row of zeros.
 Shift your results one column to the left as you move to a new multiplier digit.
 Add the results together using binary addition to find the product.
