Multiplying Two Digits by Two Digits

Grade 4 · Math · Multi-Digit Multiplication · Prince Edward Island, Canada

Lesson Summary

Multiply two two-digit numbers together using partial products or the standard method. This builds on the skills from the earlier lessons.

Explanation

To multiply 36 × 24, first multiply 36 × 4 to get 144. Then multiply 36 × 20 to get 720. Add the two partial products: 144 + 720 = 864. When you write this out vertically, you put a zero in the ones place on the second line because you are really multiplying by 20, not 2. This is the same method adults use and is sometimes called the standard algorithm.
