How do people type in mathematical symbols on Yahoo! Answers?

Question

Mathematical symbols like the square root sign (instead of sqrt(x) or x^(1/2)), pi, etc.

Answer 1

The easiest way to type them HERE is to make sure your Number Lock is on. Then. while holding Alt type the 3 numbers in the number pad on the right. Then release Alt.
224 gives α
225 ß
226 Γ
227 π
228 Σ
229 σ
230 µ
231 τ
232 Φ
233 Θ
236 ∞
241 ±
242 ≥
243 ≤
246 ÷
247 ≈
248 °
251 √
253 ²

Answer 2

Hey there!

There are two ways to create the symbols.

The first way is what lithiumdeuteride said.

1) Go to Microsoft Word.
2) Click Insert.
3) Click Symbol.
4) Choose the symbol and double click it.
5) Highlight the symbol and do the following sequence. ctrl+C.
6) Go to yahoo! answers and do ctrl+V.
7) You now have a symbol.
8) Celebrate and shout for success!

The second way is more complicated, but it follows the same as the first way, so don't worry about it!

Hope it helps!

Answer 3

The square root sign is made by holding down one of the ALT keys, and typing 251, and looks like this :√

The superscript square symbol (little 2) is made by holding down one of the ALT keys, and typing 253, and looks like this : ²

The plus or minus sign is made by holding down one of the ALT keys, and typing 241, and looks like this : ±

I'm sure other symbols are possible, but these are the ones I have found and used so far.

I just started trying numbers with ALT held down, and it looks like you could find just about any symbol you need this way!

Here are ALT 1 through ALT 10 : ☺☻♥♦♣♠•◘○◙

Answer 4

Since I tend to get a little loquacious at times, I tend to go off line and do my work in Word. When I get an answer, I cut everything from Word to this site.

Some set-theoretical notation doesn't paste, but the common stuff...
⁻¹, ⁿ exponents
₂₀₁ subscripts,
≠≅≇≉≈≉√∡∠∟∥∦∛∜≤<≥>± and other common symbols do ok.
The thing I miss is the ability to transmit graphics. It would help describing some trig or geometry problems and solutions.

Answer 5

You can get some like this: put an & sign before and a ; after each abbreviation √ is radic ± is plusmn ≤ is le ≥ is ge π is pi ° is deg ≈ is asymp or play around with alt then a number then let go: here are some ■²ⁿ ☺☻♥♦♣♠•◘○◙♂♀♪♫☼►◄↕‼¶§▬↨↑↓╚╔╙▌⌠⌡ΘΩδε∟↔

Answer 6

If you use Windows, you can use the Character Map to copy and paste symbols. It's found under Start - Programs - Accessories - System Tools.

Answer 7

Learning the codes that create these:
√ = & radic -->type that into the field when you do the question/answer... (with no space :) I couldn't get it to not do square root otherwise).
