9 × 8 = 72

9 multiplied by 8 equals 72

This shows 9 columns × 8 rows = 72 circles in total

Each row has 9 circles, and there are 8 rows

9 × 8 = 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 72

Adding row 1 of 8...

Additional information how to quickly calculate this multiplication:

  1. 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):
    9 × 8 = ((9-5) + (8-5)) × 10 + (10-9) × (10-8)
    = ((4 + 3) × 10) + (1 × 2)
    = (7 × 10) + 2
    = 72
  2. Plus method:
    If you know 9 × 7 = 63, then 9 × 8 = 63 + 9 = 72
  3. By 2 method:
    Since 8 is even, if you know 9 × 4 = 36, then 9 × 8 = 36 × 2 = 72
  4. Minus method:
    If you know 9 × 9 = 81, then 9 × 8 = 81 - 9 = 72
