Long multiplication multiplies by each digit of the second number, shifting each partial product left.

The math behind it

Multiply the top number by each digit of the bottom number, shift according to place value, then add the partial products.

Worked Example

234 × 56 = 13104.

Frequently Asked Questions

Why shift each row?

Because each digit represents a different place value (ones, tens, hundreds…).
