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):
7 × 9 = ((7-5) + (9-5)) × 10 + (10-7) × (10-9)
= ((2 + 4) × 10) + (3 × 1)
= (6 × 10) + 3
= 63 - Plus method:
If you know 7 × 8 = 56, then 7 × 9 = 56 + 7 = 63 - Minus method:
If you know 7 × 10 = 70, then 7 × 9 = 70 - 7 = 63
