I gotta get one of these for maths!

Hmm, too expensive for me:  I got one with 42 functions for \$8 (I remember when the first ones came out with 4 functions: add, subtract, multiply, and divide and they were like \$200 or more).

I bought a pen and a notepad for \$3. Beats all of your calculators!

Meh, they give them out free now (the 4 function ones) if you visit certain companies LOL

Weird... it's commonly used in Europe.

We actually started with "/" and then in highschool you work with ":"

Well, I don't think there is one in the printable "ASCII" code table, is there?  The dash with a dot above and below it.

no, what they use in ASCII,  IIRC is the / sign for division.

symbol isn't represented, unless it is in the extended ones.
