HUNDREDS.
The ONES were peasants who kept the villages running.
The Tens were ten times taller than the Ones. They were royalty who ruled over
towns and cities.
The HUNDREDS were ten times larger than the Tens and, therefore, one hundred
times greater than the Ones. Because of their enormous size, they watched over

brothers, Prince Addition and Prince Subtraction.
