That actually makes sense.

You're giving Mr Recorde a little too much credit, by the way.

Was it the use of "x"?

Was he French or Belgian? (I'm assuming you haven't changed the spelling of his given name, eg from Roberto to Robert.)

Shayne Parkinson · 03-11-2013, 04:59 AM

No, not "x", but a good suggestion! Clue: you almost certainly encountered this invention even earlier than you did the use of "x".

Not French or Belgian, and I haven't changed the spelling of his name.

I'm about to head for bed. Further clues in the morning if necessary.

The plus sign? Using the cross for adition?

Or, more general, all these signs, + - * : ?

Was it the " number" zero?

poohbear_nc · 03-11-2013, 09:48 AM

The infinity symbol: ∞?

orlok · 03-11-2013, 10:11 AM

π? ......

I thought that 'zero' was invented by gambling casinos to make Roulette a guaranteed money-maker for the house. It sure got my money...

And don't you just love the later "innovation" of the double zero? That one really took the cake (and my cash).

You're very, very close, Billi.

Not that, either.

Square root?

Bilbo1967 · 03-11-2013, 04:22 PM

Looking at Biili's very close guesses, it looks like = and / were missing. Is it one/both of those?

We have a winner! Specifically, the = sign. In his 1557 treatise The Whetstone of Witte, Robert Recorde introduced this sign thus:

Quote:

To avoide the tediouse repetition of these woordes: is equal to: I will sette as I doe often in woorke use, a paire of paralleles, or gemowe lines of one lengthe: bicause noe .2. thynges, can be moare equalle.

I came across a reference to this in New Scientist. I found it interesting that we have such a specific record of the introduction of something as fundamental as this.

Wikipedia also credits Recorde with inventing the + sign, but that appears quite a bit earlier in various German texts. Recorde does, however, appear to have been the first to use the + and - signs in a printed English text. The same Whetstone of Witte includes:

Quote:

There be other 2 signes in often use of which the first is made thus + and betokeneth more: the other is thus made - and betokeneth lesse.

Recorde's country of birth was Wales. Fbone got the date, Bilbo has the symbol. Have at it, gentlemen.

It's interesting and surprising that the equal sign has been "invented" this late. I would have thought that the old Greeks used it already. Nice question!

Yes, I thought so too! It's only a few hundred years old.
