Keyboard Question.

Why don't keyboards have the division sign on them? Well, mine don't. Does yours? I hope this is in the right section!

My keyboards division sign is the forward slash above the 8 on the number panel on the right.

They do - it is the / symbol.

100/10=10

No idea, but here's one for you ÷

That's Alt+0247

[cupid04]

Thank you. I have the / but not the division sign!

[hc4361]

Cupid, that IS the division sign

[cupid04]

Ok keep your hair on, lol! Looks like a slash sign to me. But then I'm hopeless with computers!

You do not need the division sign, just "/" as above. If you want to use your pc as a calculator, just use Excel or other spreadheet - these use "/" and would not recognise the divide sign if you had it. Note that Rachel Riley on Countdown uses "/". The divide sign seems due for extinction.
SIQ.

If you need a quick calculator just type the equation in the google search box and you'll get your answer straight away.

Thank you.

Cupid, if you need to put a maths sign of any kind into, say. a word document, look for 'insert > symbol' - on my old version of word its a drop-down top left of screen but on newer versions it will be under the tab marked 'insert'.

In this option you'll find anything you want.

I find this a very handy option, when preparing notes for lessons that require , say. 'degrees' (the little circle'), or a foreign letter like a german o with an umlaut over it.

A dash, - most certainly isn't the same as a division sign. If I use alt and 0247, nothing happens, apart from my PC "donging" at me. If I use AltGr and 0247, I get €.

But I can get it by using the numeric keyboard on the right though, not the one above QWERTY .....÷

Its important to realise that there are two 0247's on some keyboards.

It is nothing to do with the keyboard. The keys on the keyboard simply send scan codes. They are converted to characters via the character map.

There are two different 0247s because the numeric keypad and the numbers in the main keyboard are different keys despite having the same characters mapped.

The Alt is combined with the keyboard scan codes to produce other characters, not with the character map.

The character map can be altered such that any key can be made mapped to any character. That is what happens in different language keyboards.

Both the divide sign and the use of X for multiplication have been deprecated for a long time in computer maths.

Multiplication is the asterisk *
Division is the forward slash /
(Integer division is the backslash \ in some programs)
Exponentiation is done with the caret ^ rather than superscript.
Roots are often expressed as a fractional exponent.

what's '0247'?
