what does the p and q stand for in mind your p's and q's
Mind your Ps and Qs Nevertheless, a number of alternative explanations have been considered as more or less plausible. Another explanation suggests that "Ps and Qs" is short for "pleases" and "thank-yous", the latter of which contains a sound similar to the pronunciation of the name of the letter "Q". Another proposed origin is from the English pubs and taverns of the 17th century. Bartenders would keep a watch on the alcohol consumption of the patrons; keeping an eye on the pints and quarts that were consumed. As a reminder to the patrons, the bartender would recommend they "mind their Ps and Qs".[3] This may also have been a reminder to bartenders not to confuse the two units, written as "p" and "q" on the tally slate.[4]

Using any of the above rules in the order "addition first, subtraction afterward" would incorrectly evaluate the expression[6]
