Figure Counting Tricks
- Small triangle (Δ) = 5
- Large triangle (Δ) = 5
- Example calculation: 8 + 8 + 3 + 3 + 3 =25. Large triangle = 4, therefore 25 + 4 = 29
More Figure Counting Tricks
- Another example: 5 x 9 = 10, â–³ of star = 10, 10 + 3 + 1 = 14
- Example: 8 x 3 = 24 + 4 = 28, large triangle (Δ) = 8, 28 + 8 = 37
- Example: √4 + 1 = 5, small triangle (Δ) = 4, big triangle (Δ) = 5
