Numerical and Chronological Order
Strings representing numbers may be sorted based on the values of the numbers that they represent. For example, "-4", "2.5", "10", "89", "30,000". Note that pure application of this method may provide only a partial ordering on the strings, since different strings can represent the same number (as with "2" and "2.0", or when scientific notation is used, "2e3" and "2000").
A similar approach may be taken with strings representing dates or other items that can be ordered chronologically or in some other natural fashion.

“The moment a mere numerical superiority by either states or voters in this country proceeds to ignore the needs and desires of the minority, and for their own selfish purpose or advancement, hamper or oppress that minority, or debar them in any way from equal privileges and equal rights—that moment will mark the failure of our constitutional system.”
—Franklin D. Roosevelt (1882–1945)
“In order to succeed in a profession, a person not only needs to have its good, but also its bad qualities. The former are the spirit, the latter is the body of the job.”
