From 21 × 2 all the way up to 999 × 999: multiply by each digit, write the partial products, and add.

Built for 5th graders — and for homeschool parents who need to teach it this week. ⏱️ CHAPTERS 0:00 What we're covering 0:11 Example 1: 21 × 2 2:47 Example 2: 34 × 13 6:32 Example 3: 345 × 26 10:04 Example 4: 986 × 57 13:10 Example 5: 999 × 999 18:19 Summary The mistake to unlearn: forgetting the placeholder zero. When you multiply by the 3 in 13 you're really multiplying by 30, so the second row shifts one place left. Skip the zero and 34 × 13 comes out as 136 instead of 442.
