New!  Inline Math Editor

Problem-Attic has made the writing of math and science questions faster than ever!  A new option for “live” or inline math provides all kinds of shortcuts plus automatic on-screen preview.

The inline math editor is based on MathQuill, a popular program for adding formulas and special symbols to a web page.  You might be familiar with MathQuill already if you’ve used the Desmos graphing calculator or various assessment tools by Learnosity.  Problem-Attic’s implementation goes a bit further with:

Below you’ll find a quick introduction to the editor and all the details for producing beautiful-looking formulas for math and science.  Please give it a try.  You’ll not find a quicker or more intuitive way to type math on the web!

Please note:  the new math editor is a subscription feature in Problem-Attic.  However, you can use it as often as you like, free of charge, in what’s called the Play Area.  Click here to learn more.

Getting started

The inline math editor is an alternative to the palette-based, or pop-up, math editor in Problem-Attic.  The latter is still available.  In fact, you should continue using it for complex, multi-line formulas.  For most other formulas and special symbols, and for mixing math and regular text, you’ll find the inline editor to be faster.  Here’s an example of what to do:

  1. Start or open a document in Problem-Attic.

  2. Go to Arrange and click the button Write New Problem.

  3. Once you’re inside the problem editor, type some text, like “Simplify.”

  4. Press Ctrl-M (Windows) or Cmd-M (Macintosh) to start inline math.  Type the following, where ◾ means press either the Spacebar or Tab key.

    1 / 2 ◾ x \d ◾ 6 x ^ 2

  5. Press Ctrl-M or Cmd-M to stop inline math.  You should see the same formula as in the picture below.

Notice how you typed \d for a divide sign?  Most other common symbols can be typed similarly, with a backslash followed by one or more letters, such as \t for a times dot and \x for a times cross.  These are called “commands”.  A fraction can be created with a forward-slash or the command \f.  You can create a radical with \r and an indexed radical with \ir.

If you are familiar with LaTeX, many of its commands also work in the inline math editor.  You have the option of using LaTeX or abbreviated commands, such as those described above.  The results are the same.  Full written-out commands, like \fraction, are also available.

For a list of all supported commands, abbreviated, written-out and standard LaTeX, please see these charts.

What’s ahead

You’ll certainly agree that “live” math editing is a great improvement to Problem-Attic, and you’ll probably want us to take it even further.  We’re with you on that!  Here some things still in the works:

That’s it for instructions.  Now please, go try the inline math editor and remember, if you’re not a subscriber to Problem-Attic, it’s available for free in the Play Area.  If you are a subscriber, thank you!  Your support makes improvements like this possible.
