Well here are ALL the programs that I use going from free and standard to paying money.\n\n\nCharacter Map (under system tools)\nEquation Editor (in Word)\nLaTeX (search on web and download)\n\nMathType actually extends your Equation Editor and is a program to use in Word and it is NOT free ( http://www.dessci.com/en/products/mathtype/ )\n\nDerive\nMaple\nMatLab\nMathematica\nand any other symbolic software you can purchase

you can go to "inset" then "symbol" and find it there. Or  alt - 0153

If you're ready for LaTeX, there are modules in there for drawing chemical symbols. Be ready for a steep learning cycle though, but once gone through it, you may wish you had gone through it earlier.\n\nIf you belong to the 90% Microsoft addicts among current computer users, you can safely ignore this message.

you can use the normal calculator of windows for these conversions.\n\nOptions are only available in a scientific view of the calculator.

If you don't have MS WORD or WORDPERFECT, try this "office suite" from http://www.openoffice.org , it's from sun microsystems to allow you write, draw, math, calculate and much more. It's free to use.\nor\nIf you have email, just type it in web-based email or email client like outlook or outlook express, and print it out after you finish.

Ctrl + 13 gets you one.  \n\nAlso, you can go to "start" "programs" "accessories" "system tools" then "Character Map."  You will find most of them under "symbols."\n\nGood Luck

hold alt and type on the number pad 227 π

I don't think that's available as a font or special character.  You may have to either download a font that has mathematical symbols or insert it using the Equation Editor.  If you go to Insert-Object, look for something like Microsoft Equation 3.0.  There you can insert all sorts of mathematical things - matrices, summations, etc. - including your x-bar.

♥Go to>start>programs>accessories>system tools> then "Character Map"...scroll down to "symbols."\n\nHope that helps.\n\nMore info:\nHold down the ALT key and then press numbers on the num pad. When you let go, it will type a symbol such as this smiley face: ☺ (ALT + 1).\nA heart is ALT + 3: ♥. You can press more than one number, though, such as ALT + 1 + 3: ♪. Similar things are usually grouped together, so ♥ is ALT + 3, ♦ is ALT + 4, ♣ is ALT + 5, and ♠ is ALT + 6. Experiment and you will find many more.\n\nAnother way of doing it is to type special codes for certain entities such as &hearts ; (without the space inbetween the code and the semicolon) which is ♥. Here is a list of a bunch of them: http://www.htmlhelp.com/reference/html40...\n\nIf you're using Windows then a third way is to go to start > all programs > accessories > system tools > and character map (or just go to run and enter charmap). Then search for what you want, select it, copy it, and paste it wherever you want. For example, I found this in character map: ♫. I found this under another answer. \nwww.asciitable.com\n\n♥♥

Hit the "Math" Button (hit "2nd", then "x") press the "right" arrow and you should see "abs(" and select that and hit enter.

If you're using windows.\n\nStart > All Programs > Accessories > System Tools > Character Map\n\nYou will find the heart as well as other symbols in there to copy and paste.

Use Word's integrated equation editor:\n\nInsert > Object > Microsoft Equation 3.0\n\nThis will launch an equation editor that will allow you to put in almost any mathematical symbol/number, etc.\n\nHope this helps.

You can go to START>>PROGRAMS>>ACCESSORIES>>SYSTEM TOOLS>>CHARACTER MAP>> then choose the symbol from the list and click copy.\n\nOr do what Mikah said.
