Crafty Grandma Edith sat her family down during Thanksgiving and told them they couldn’t have any pumpkin pie until they worked out this puzzle. Her 6-year-old granddaughter was the first to solve it! Can you work out what 9183 equals?


8809 = 6 3590 = 2

7111 = 0 6855 = 3

9881 = 5 1012 = 1

6660 = 4 5731 = 0

5531 = 0 9191 = 2

2516 = 1 9183 = ?


I'm really confused about this one, could anyone help me?
