YOUR ANSWER: Any number is equal to any number.
The statement you chose is not completely clear. It depends on what you mean by "any number." If you meant "any number is equal to that same number," then your statement would sum up the table, since
1 = 1
2 = 2
3 = 3
etc
But we could read your statement to mean "any number is equal to any other number," which would be nonsense and would not get across the idea that we were trying to show with our table.
One of the statements on page 23 sums up our table quite exactly. Return to page 23 and pick it out.
