Question

Javier cut a piece into 10 parts. Then he took one of the pieces and also cut it into 10 pieces. He did this two more times. How many pieces of paper did he have left at the end?

Answer 1

The answer is 37

Explanation:

he started with 10 parts. He took one of those 10 so he was left with 9 on the table , then he cut the one into 10 so 10+9= 19. He did the same 2 more times , it means that he took one of the 19 , so 18 on the table and he cut the one into 10 ,therefore, 28. Then he did it one last time , he took one of the 28 so 27 on the table , he cut the one and then finally 27+10= 37 pieces.

Its hard to explain but I think you'll get the idea.
