There are 7 parent tigers
Parents = 7
7 tigers each have 7 children. That means there's total of 7 × 7 children.
Children = 7 × 7 = 49
Each child has 7 friends. That means there's total of 49 × 7 friends.
Friends = 49 × 7 = 343
Total = 7 + 49 +343 = 399 TIGERS
I'm not a tiger so I'm not counting myself.
