A binary multiplier is an electronic circuit used in digital electronics, such as a computer, to multiply two binary numbers. The lattice method is an alternative to long multiplication for numbers. In this approach, a lattice is first constructed, sized to fit the numbers being multiplied. If we are multiplying an -digit number by an -digit number, the size of the lattice is .
