the guestion was: proof that half of the number nine(9)
is four

Hello, khotso!

Finally . . . a corrected version of the problem!

Prove that half of nine is four.

Use toothpicks and Roman numerals.

Code:

      |   \     /
      |    \   /
      |     \ /
      |      *          We have "nine".
      |     / \
      |    /   \
      |   /     \

Code:

      |   \     /
      |    \   /
      |     \ /
    - + - - -* - - -    "Half of nine"
      |     / \
      |    /   \
      |   /     \

Code:

      |   \     /
      |    \   /          "Four"
      |     \ /
      |      *

      |     / \
      |    /   \
      |   /     \

Code:

      |   \     /

Did you formally study toothpick analysis in school?

Actually, I majored in Toothpick Analysis
