How to Insert Equations & Formulas At using Open Office


How do you do that in OpenOffice?
The first step is to just go to the old reliable Insert menu. Anything out of the realm of plain text, just go to the Insert menu.
Just Using the Special Characters Window
Now, if you just want a Special Character, pi or lambda or something, you can choose Insert > Special Character.
Sc1_1
Find the one you want. If you select several you'll see them all displayed at the right side of the window and they'll all be inserted.
Then just click Insert. The character will show up.
Sc2
It's a pain to scroll through all that again and again so make an AutoText entry for it. See
Using the Formulas Features
If you need something more complex, then instead, choose Insert > Object > Formula.
You get an editing window at the bottom, a box for the equation in the document, and a little shortcut window floating off to the side.
F1
Now,  you can use the little shorcut window. Click an item above the line, then click an item below the line and that inserts some placeholder stuff for you in the editing window.

But frankly I find it not that helpful since just writing the formulas is reasonably easy once you memorize a few tips.
  • Use the Formula Reference Tables online help list to see how to enter formulas. Basically, do it how you think it would work. Use the OpenOffice.org Math Examples online  help list to see examples. These are really good. Just press F1 while you're in the editing window; you can type the titles of these topics into the Find or Index window.
  • Use ^ for exponents, as in 3^2  which would be three, squared.
  • Use sqrt for square root
  • Use % in front of the written version of a symbol, as in %pi
So here are a few formulas. They're pretty easy to figure out. Click each image to see a slightly larger version, if you like.
a + b / $pi
F3bdivides
a + b over $pi
F4
(a + b) over $pi
F5parens

If You Don't Know How to Write Out a Character Like %pi or %rho
Click the Sigma icon at the top to add a special character.
F6epsilon
You can just scroll  through and select something from the list, and insert it.
F8window
Or you can add something yourself if you don't see what you need.
Optional: Add your own symbol   
To add something you don't see, click Edit.
F8window
Find what you want, by scrolling and manipulating all the dropdowns. Then name it, and click Add, not Edit.
F9add
The new symbol will show up in the symbol list.
F10addshowsupinlist
Click in the document to stop editing the formula.
If you want to get back into the formula to change it, double-click the box the formula is in.
Formatting the Formula
All right. You've got a great formula. But it's really small. Or you'd like a different font. You change these by selecting the formula in the editing window and click on the Format menu.
F_formats_1
Choosing Fonts gives you this window. You get to choose the font by the type: variables, etc. Click and hold down on the Modify button to change any font.
F_12fonts2
Select the font in this window, then click OK all the way back out of the windows.
F_font15_1

That's About It
Insert > Object > Formula. Type what you want and use the online help and the brief tips I gave you.
Click in the document when you're done, and double-click the equation box to start editing again.
To format, select the text in the editing box and find the Format menu.
To add a symbol you don't know, click the Epsilon icon at the top of the window and select one--or click Edit to create your own.
Doing All This in Impress
I'm using 2.1 in February 2007 and it works just fine.
Click in a bulleted item and choose Insert > Object > Formula.
Inserting
You can also paste the formula object from Writer to Impress. Don't paste it into a bullet in this case; just paste it into a layout with no bullets.
Editinginimpress
Double-click to edit, as usual.
Insertinginimss
Double-click the formula object to get into edit mode. Use the Format menu or make other changes.
