Intro: Multiplying With Digits Up To 999

Multiplying larger numbers using place value and partial products

This lesson shows how to multiply whole numbers with up to three digits (values up to 999). It builds from place value and the area model into partial products, then into the standard column multiplication algorithm, using fully worked examples so you can check every step, including carrying and place-value shifting.

Overview

Multiplying with Digits up to 999

What You'll Learn

Break each factor into hundreds, tens, and ones before multiplying, such as writing 236 as \( 200 + 30 + 6 \)

Use an area model to multiply each part of one factor by each part of the other, then add the partial products

Apply the standard column algorithm, multiplying by the ones digit first and then the tens digit with a zero placeholder shift

Carry correctly when a partial product in any column is 10 or more

Check a three-digit by two-digit product like \( 236 \times 34 = 8024 \) by adding the partial products \( 944 + 7080 \)

Extend the same method to three-digit by three-digit multiplication by adding a third partial product row
