There will be many times this year (and in future years) where you're going to want to create some mathematical notation for use on a blog, wiki, Moodle or something else that's difficult to just "type" on a keyboard. There are many different ways to do this, I've listed just a few below. Unless it just doesn't work for you, I highly recommend using Option 1 (Daum Equation Editor in Chrome).

**Option 1**: Use Chrome Apps/Extensions

There are a variety of Chrome Apps that will let you create math notation. One of the best, and easiest, is

Daum Equation Editor.

First, make sure you're in Chrome (if you don't have Chrome,

install it).

Create your equation (I think you can figure out how to use it fairly easily, but ask if you need help).

After you've created, click Save as Image or Save to Google Drive in the lower right corner.

Insert the image into your blog/wiki/moodle.

**Option 2**: If you have a Tablet (like an iPad or similar), simply draw the notation and save it as an image, then upload that image.

**Option 3**: Use an online equation editor, like

this one.

Create your mathematical expression/equation, choose "png" from the drop-down where it currently says "gif", then click on "Click here to Download Image (png)" to download the image. Then insert it into your blog/wiki/Moodle/etc. by using the insert/upload image button.

**Option 4**: Scan or take Digital Picture.

Write out your mathematical expression/equation on paper and either scan it or take a digital picture, then insert it into your blog/wiki/Moodle/etc., by using the insert/upload image button.

**Option 5**: Use Microsoft Word/Open Office/Libre Office and a screencapture utility.

Microsoft Word,

Open Office and

Libre Office have equation editors built-in to them. You'll need to explore a bit to find them (the help system is great to help you find it, or check out these docs:

Microsoft Office (find your version),

Open Office,

Libre Office). Try creating some expressions/equations, perhaps with fractions in them. Once you can see your completed expression/equation on the screen, you'll need to capture it using a screen utility.

**Mac**: Use

Grab (comes with OS X). Launch Grab and drag a selection rectangle around the expressions/equation and let go. Grab will grab a screenshot of what you had the rectangle around. Once the image is in Grab, you may be able to copy and paste into some things (like a blog post). More likely, you'll need to save the image and then insert it. In Grab, it will automatically save as a PDF. Then you'll need to open it in Preview on the Mac, choose Save As, then choose JPG or PNG from the format choices. Once you save it as a JPG or PNG, you can insert it into your blog/wiki/Moodle/etc. by using the insert/upload image button

**Windows 7**: Windows 7 has a built-in

Snipping Tool. Capture your expression/equation, and you may be able to copy and then paste it into some things (like a blog post). More likely, you'll need to save the image and then insert it. Save it as a JPG or PNG, then insert it into your blog/wiki/Moodle/etc. by using the insert/upload image button.

**Ubermix Linux**: Use

Screenshot. Capture your expression/equation, and you may be able to copy and then paste it into some things (like a blog post). More likely, you'll need to save the image and then insert it. Save it as a JPG or PNG, then insert it into your blog/wiki/Moodle/etc. by using the insert/upload image button.

**Option 6**: Install MathType.

You can download and install

MathType for free on a Windows or Macintosh computer. It will be a fully functional version for 30 days, and then will revert to MathType Lite, but that's okay because the Lite version has everything we need. While MathType should be safe, please ask your parents before installing any software on your computer at home.

After installing MathType you'll need to launch it and change a setting so that you can copy and paste to your blog (these instructions accurate at the time I created this - they could change).

**Mac**: Go to the MathType Menu, then Preferences, then Cut and Copy Preferences. Select "Equation for application or website" and in the drop-down menu choose "Google Docs" and then click "OK".

**Windows**: Go to the Preferences Menu, then Cut and Copy Preferences. Select "Equation for application or website" and in the drop-down menu choose "Google Docs" and then click "OK".

Now play around in MathType and try creating some equations, perhaps with fractions in them, and you may be able to copy and then paste it into some things (like a blog post). More likely, you'll need to save the image and then insert it. Save it as a JPG or PNG, then insert it into your blog/wiki/Moodle/etc. by using the insert/upload image button.

**Option 7**: Some other option you know of that works better for you.

If you find one you really like, please share it with me and I'll add it to this page.

There are also a variety of online calculators that you may want to use to create expressions/equations/graphs and then screenshot them, including:

Desmos Graphing Calculator (also pretty decent scientific, click "show more" on the keypad to get additional functions) (or Chrome App version of it)

Wolfram Alpha
