Multiplication Setup
Pick direction and enter binary numbers
Which multiplication?
Binary multiplication uses partial products: multiply A by each bit of B (shifted left), then sum all partial products.
Result
Enter values to see result
Enter binary numbers to see the multiplication result.
The product length can be up to len(A) + len(B) bits. Binary multiplication is commutative: A × B = B × A.
How to Use
- Select direction :- Choose A × B or B × A
- Enter binary A :- Type a binary number (0s and 1s only)
- Enter binary B :- Type a second binary number (0s and 1s only)
- Click Calculate :- View the product with partial products and step-by-step breakdown
Note: Each bit of B is multiplied by A, then shifted left by its position. The final product is the sum of all shifted partial products.
