Binary multiplication has 4 basic rules:

• 0 × 0 = 0
• 0 × 1 = 0
• 1 × 0 = 0
• 1 × 1 = 1

Binary numbers allow for the same arithmetic calculations as numbers from the decimal system. Addition, subtraction, multiplication, and division are easily performed with binary numbers. Additionally, bitwise operations like bit shifts, logical AND, OR, and XOR can be executed.

To multiply binary numbers, follow these steps:

1. Set the longer number as the multiplier and the shorter number as the multiplicand.
2. Multiply the multiplier by each digit of the multiplicand to achieve intermediate products, whose last digit is in the position of the corresponding multiplicand digit.
3. Sum the intermediate products to get the final product.
