Multiplication by 8, step by step
The eight times table is doubling done three times, which means a child who can double already holds every fact on this page.
The question
8 × 8
8×8
8 × 8=8 × 8
8 × 5=40
8 × 3=24
40+24=64
8×8=64
- 8 × 8 means 8 groups with 8 in each one — 8 rows of 8. The answer counts everything in all of them, not one row.
- Added up, that is 8 written 8 times — nobody wants to do that. Turn it round: 8 × 8 is the same amount, and it is only 8 lots of 8 to add instead.
- If 8 × 8 will not come, split the 8 at five: 8 × 5 = 40, and 8 × 3 = 24. Together that is 40 + 24 = 64.
- So 8 × 8 = 64.
