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.
