Insertion of a bolt or nut is clockwise (right), turn counterclockwise (left) to get a bolt or nut off of something. ("Right on" may be outdated slang; it means something is very good.)

* Righty tighty, lefty loosie

Mnemonics - Arithmetic

**A Rat In The House Might Eat The Ice Cream: Arithmetic

* Sir, I send a rhyme excelling
In sacred truth and rigid spelling
Numerical sprites elucidate
For me the lexicon's dull weight.
Counting the letters of each word gives you the value of pi to the 20th place. The thing I like about this mnemonic is that it actually makes sense! By the way, if you want to know pi to the umptieth place, you can find that info at UCLA. You can also find a whole pagefull of interesting Pi stuff at The Pi Page or Antreas' page. Amazing what's out there on the Web, isn't it?

* May I have a large container of coffee?

January (knuckle), February (space), March (knuckle), April (space), May (knuckle), June (space), July (knuckle), August (knuckle), September (space), October (knuckle), November (space), December (knuckle).

NOTE: July and August are where your two hands are put together! All the months on the knuckle have 31 days the ones that land on the space have 30--except of course February! This info supplied by Darlene.K.Carlson.2@nd.edu, a veritable fount of information!

* A neighbor battle ended.
These two use the same technique as above, to remember that the American Civil War ended in 1865.
