MULTIPLYING TECHNIQUE

THERE IS A WAY OF MULTIPLYING BY NINES ON YOUR HANDS.
ALL YOU HAVE TO DO IS HOLD UP YOUR TEN FINGERS AND PICK THE NUMBER
THAT YOU WANT TO MULTIPLY NINE BY AND THEN YOU PUSH DOWN THAT FINGER.
FOR EXAMPLE, IF YOU WANT TO MULTIPLY NINE BY THREE YOU WOULD PUT
DOWN YOUR THIRD FINGER.
ON ONE SIDE OF THIS THIRD FINGER YOU WOULD HAVE TWO FINGERS HELD
UP, ON THE OTHER SIDE YOU WOULD HAVE SEVEN FINGERS HELD UP,
THEREFORE YOUR ANSWER WOULD BE TWENTY-SEVEN.
