New Mathematical Breakthrough!

This morning David decided to distract Emmaline from her pestering for roasted marshmallows by asking her addition questions.  He asked her, "Emmie, what's one plus two?".  I reminded her of the way I had shown her for solving simple addition questions: hold up the amount of fingers for the first number on one hand, and the appropriate number of fingers for the other; then bring them together and count.  She did so, counted, then told her Daddy, "Free!!(Three)".  Impressed by her counting skills, David asked her, "What's two plus two?".  She held up two fingers on each hand brought her hands together and said, "It's W!!!!".  And there you have it folks: the newest mathematical breakthrough is two plus two makes W.
