Long Multiplication Calculator
Enter two whole numbers — see the partial product for every digit of the second number and their sum, just like the school column method.
How to use
- Enter two whole numbers, for example 246 and 35.
- Watch the result update live — no button to press.
- Read the partial product for each digit of the second number, shown with its place value.
- See the final sum of all partial products at the end — that is the answer.
Note: Every partial product comes from one digit of the second number, with zeros added based on its place (tens, hundreds).
Tips
- Check homework with this tool — the steps follow the school column method exactly.
- The second number's length decides the steps: one partial product per digit.
- Negative numbers work too; the answer's sign follows normal multiplication rules.
