How to show in Yahoo Answers the term x squared other than x^2?

Answer 1

x²

Assuming you are running Windows, then you can do the following:

Press 'NumLock' then hold down 'Alt' and type 253 on the numeric keypad. Then release 'Alt. key.

There are lots of math symbols you can make this way:
Greek Symbols:
α = Alt-224
ß = Alt-225
π = Alt-227
Σ = Alt-228
Φ = Alt-232
Θ = Alt-233

Math Symbols:
∞ = Alt-236
± = Alt-241
≥ = Alt-242
≤ = Alt-243
÷ = Alt-246
≈ = Alt-247
° = Alt-248
√= Alt-251
² = Alt-253

There are even more symbols if you use leading zeroes combinations. (See the linked Wikipedia article).

You can also use the Character Map utility in Windows to pick symbols and paste them into a question or answer. You can find it under:

Start > All Programs > Accessories > System Tools > Character Map

Answer 2

Nice question. Here's another way:
Change your default keyboard to
United States-International.
Then to get the exponent 2, hold down
the right ALT key and type 2.
You can also get an exponent of 3 this way
by hitting right ALT and 3.

Answer 3

Holding Alt and typing in 253:

Answer 4

If you don't want to resort to superscripts then x**2 is perfectly valid, as used in Algol and Fortan.

Answer 5

This has been bugging me too!! Thanks to Puzzling & others on the [alt]-code, option.


I cannot get character map to work right. I select, then copy; but when I paste, the result is nothing. Num Lock is enabled. (my e-mail is available.)
