In the forest there is a Deca Tree.
A Deca Tree has 10 trunks,
and on each trunk there are 10 branches,
and on each branch there are 10 twigs,
and on each twig there are 10 leaves:

Then he cut off one branch from another trunk of the tree.
Then he cut off one twig from another branch.
Finally he pulled one leaf from another twig.
