Additional information how to quickly calculate this multiplication:
- Hand method:
For numbers between 5 and 10, you can use this special method (this looks easier when visualized using palms, I will explain it later):
8 × 8 = ((8-5) + (8-5)) × 10 + (10-8) × (10-8)
= ((3 + 3) × 10) + (2 × 2)
= (6 × 10) + 4
= 64 - Plus method:
If you know 8 × 7 = 56, then 8 × 8 = 56 + 8 = 64 - By 2 method:
Since 8 is even, if you know 8 × 4 = 32, then 8 × 8 = 32 × 2 = 64 - Minus method:
If you know 8 × 9 = 72, then 8 × 8 = 72 - 8 = 64
