Thought the hint was a bit of a red herring. Immediately thought of neutrons and nuclei. Good answer though.

I started thinking of Sherlock Holmes stories (just what were the names of the original

books - did any of them fit A. N.?), thinking that S could stand for stories. I also thought about properties of elementary

schools.

A friend of mine was brought up in Saudi Arabia and moved to England at about age 10.. he was told to write the answer to an equasion in arabic numerals.... and then told off when the teacher couldn't understand all the backwards scribbles. >.<

oh yea, elementary...

EASY!

It was hard for me!

To Atropos - Huh? The numerals we use ARE arabic... don't understand your story. The arabic student's answer would have looked identical to ours!

This teaser is good, but a bit obscure... Not a common phrase, but it is doable. Good job!

it was fun but it was also boerin well anywayi liked it alot and i think u guys should make anotherone like it accept kinda diferent

Nice! An actual equation that wasn't blatantly obvious.

I didn't realise that this was a well-known phrase.

A very enjoyable teaser! To musicmaker: as far as I know, our arabic numerals, though similar to the arabic-arabic ones, are not 100% the same. Plus, the student in Atropus' story would probably be writing them from left to right (since the teacher said "Arabic"...)

I mean, right to left. Doh!

I did axactly as you did, dewtell!
