The Universe in an Hourglass: A Time for Everything
The numbers one through nine (and the placeholder zero) are used in combination to create all other
numbers in a base-ten counting system. For example, the number one billion two hundred thirty-four
million five hundred sixty-seven thousand eight hundred ninety (1,234,567,890) contains the numbers
one through nine and the placeholder zero. Numbers greater than nine can be broken down into one of
the original nine numbers of value in a base-ten counting system.
For example, the number ten appears as a one and a zero (10). When one and zero are added
together they equal one (1 + 0 = 1). Likewise, a count greater then nine can be broken down to one of
the nine original numbers of value (as can all other numbers).
