Binary multiply
ClientMultiply bit strings for learning binary arithmetic beyond add/subtract.
How to use
Enter two binary numbers.
About Binary multiply
Multiply two binary numbers—decimal and binary product, local only. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.
How to use this page
Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.
101 × 11 = 1111 (15 decimal)
