Did You Know

[stewey]

..that the line which is between the numerator and denominator of a fraction is called a "solidus"? Isn't your day now complete?

[Svejk]

about 3/4

[stewey]

How common of you.

[Svejk]

^square

[baza]

no I didn't but I do now, thank you for making my life complete.

[Sqad]

I didn,t even know what a denominator or a numerator was.............some kind of sophisticated sex toy?

[RATTER15]

Between a what and a what?

[stewey]

Sqad, you're thinking of a denominatortrix.

[tamborine]

shows your multilingual & can multi task, clever d1k ;)

[stewey]

You've just made my day complete, Tambo:)

Anyway, I picked up this vital information by glancing through a copy of “Machinery’s Pocket Books For Engineering Students” published in 1969 by The Machinery Publishing Co. LTD in New England St., Brighton, Sussex. The book cost 5/-. Any of you who were in the engineering profession will remember their books as being the “Bible” of the trade.

[baza]

I remember when 5/- was a lot of money, a chip supper, a packet of fags and the tram ride home.

[stewey]

Baza, I remember as a kid saving up, it seemed for weeks, the five shillings cost of a book about planes. I don't think it was a "Janes", but something similar.

[Svejk]

there were 'plane-spotting' books about. we didnt have to write their numbers down though. lol.

[Brinjal]

Yep day is definitely complete now just have to dot the i with a tittle.

[stewey]

Is that a brand of tea, Brinjal?:)

[Buenchico]

Well since you've been kind enough to provide us with a solidus, Stewey, I'll provide you with an obelus. Here it is ÷

[stewey]

Really; that's new to me...Interesting.

And did you know, the little channel below your nose, between your nostrils is called the philtrum.

[stewey]

I think we're going off on a tangent now:) According to the aforementioned book a "decagon" is, obviously, a ten-sided figure; however, an "undecagon" is an eleven-sided figure...Now that's logical isn't it?:)

Well. You learn something every day! In future, I'll remember learning about the two words for these symbols, but by tomorrow I'll doubtless have forgotten what the words actually were! I know! I'll make a note on my iPad to remind me, in case anyone should ask. (Someone in my local pub is bound to - sooner or later!).
