"Ought" Versus "Aught"

When someone says the word "aught" meaning "zero," it is spelled with an "a." It is an old word that means "zero." In the early 1900s, many people referenced those first years as "aught six," transcribed "06."

There is an expression "for aught I care," which today is most often said "for all I care."

It is never "ought."

Happy punctuating!
