7 × 8 = 56
7 multiplied by 8 equals 56
This shows 7 columns × 8 rows = 56 circles in total
Each row has 7 circles, and there are 8 rows
7 × 8 = 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 56

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 × 8 = ((7-5) + (8-5)) × 10 + (10-7) × (10-8)
= ((2 + 3) × 10) + (3 × 2)
= (5 × 10) + 6
= 56 - Plus method:
If you know 7 × 7 = 49, then 7 × 8 = 49 + 7 = 56 - By 2 method:
Since 8 is even, if you know 7 × 4 = 28, then 7 × 8 = 28 × 2 = 56 - Minus method:
If you know 7 × 9 = 63, then 7 × 8 = 63 - 7 = 56
