Think of a number

[Factfinder]

Think of a number that if you take away 25 and square it, its the same as squaring it and taking away 25.
This is a school homework question

x is minus 13

[topspin]

I think it is +13.

[badlad]

Agree with topspin

[smouse]

and so do I
(x-25)2 = x2 � 25
x2 � 50x = 625 = x2 �25
so 50 x = 650

sorry dont know how to do superscript but the 2s with the x are squared signs

[logophile]

Yes, I agree - don't know how that minus crept in !

Smouse - Square Symbol is Alt 253 . . . eg 3� = 9

� � � � � � � � � � � � � � � � � � � � � � � �
Press your 'Alt' Key (don't let go)
Using your Number Pad press 253
Release 'Alt' Key
� � � � � � � � � � � � � � � � � � � � � � � �
Laptop users, without a Number Pad, would use:
Fn + NumLK with MJKLUIO789 representing 0-9 to access all 256 characters including additional symbols, eg ♫♂Ω
Hope this helps! ☺ja

Hi ja .. I have a laptop and have used this system following guidelines posted by you some months ago.

However, whilst I have unearthed smilies ☺ and fractions � ☺� , I have never found the combination for the musical notations, other than copy and paste.

Any suggestions ?? (S) ☺☺

Howdy S - 'CP437' or 'Code Page 437 English' is the user-unfriendly name for the original DOS Character Set, both Normal and Extended (hidden). These are numbered from 0 to 255.

If you search Google for 'Code Page 437' you should find a table you can print and retain on your desk. I just photocopied mine from an old Dos Manual.

This is too big to print - you need A4 or smaller but you might like to Bookmark it for reference. Good Luck, ☻ja

Sorry smous I don't quite follow your logic.

[smouse]

Ignore me then - lol
I was just trying to show you the working for if you needed it

Many thanks ja .. (sorry to hijack your thread Factfinder) .. whilst I can access symbols as shown for viz .. 1, 12, 20 and 21 etc etc as shown on chart, when I input 13 or 14 for musical notations I am given more smilies !!
Whilst this is not really of any importance, it is a little annoying. Cheers ☺ (S).

[johnalex]

Hi S - Yes that must be very frustrating - I can only think that the factory setting is different, with an alternative Character Set installed. I suppose you could confirm by testing a friend's laptop. If you have the patience you could print out your own Character Table Alt 1, Alt 2 . . . . Alt 255 then see how many smilies show up, which presumably represent blanks. If the currency symbols are different then maybe it is intended for use in another country. Other than that I guess you could still cut and paste from your symbols table.

Regards 2U2 Factfinder. Trespass not intended but sometimes inevitable, ja ♫♪

Thanks for your trouble ja ... I will revert to cut and paste for the present !! ♫ ♫ ♪ ♪ ♫ Cheers (S) ☺
