conversations.value: Can you give me some step-by-step instructions for this math problem: A snake's head is one-tenth its length. If a snake is 10 feet long, calculate the length of the rest of its body minus the head.

conversations.value: A snake's head is one-tenth its length, which is 1/10*10 = 1 foot.
  Since the snake's head is 1 foot, the rest of its body is 10-1 = 9 feet long.
