The Little One Learns Math

The little One is deeply saddened: Because she made
a small calculation error, she couldn’t offer enough
food to her number friends. She feels uncomfortable
that she can’t calculate as well as the other numbers.
Luckily the Master of Numbers is there to help her. He
tells her of the castle of the Numbers Fairy, where she
can finally lose her fear of math problems. But only
the one who reaches it first can claim the valuable
treasure. The number friends start a race. Their way is
full of math problems and exciting challenges. Who will
be the first to reach the castle of the Numbers Fairy?
