Understanding the result

Example: 234 × 56 = 13,104: the partial products are 234 × 6 = 1,404 and 234 × 50 = 11,700.

Frequently asked questions

Why are the partial products shifted before adding them? Each partial product corresponds to a different place value in the multiplier (ones, tens, etc.), so the tens-digit partial product is shifted one place left before summing, which is why 234 × 50 shows as 11,700 rather than 1,170.

Does this work the same way for numbers with more than two digits? Yes, the method extends to any number of digits — one partial product per digit of the multiplier, each shifted according to its place value, then summed.
