 To convert handwritten math from your notes
If you use your computer to solve math problems or to create documents or presentations that have typed mathematical expressions in them, Math Input Panel makes the process easier and more natural.
What is Math Input Panel?
Math Input Panel uses the math recognizer that's built into Windows 7 to recognize handwritten math expressions. You can then insert the recognized math into a wordprocessing or computational program.
Math Input Panel is designed to be used with a tablet pen on a Tablet PC, but you can use it with any input device, such as a touchscreen, external digitizer, or even a mouse.
To use Math Input Panel
 Tap to open Math Input Panel
 Write a wellformed math expression in the writing area.The recognized math is shown in the preview area.
 Make any necessary corrections to the math recognition. (To learn how, see "To make corrections" later in this topic.)
 Tap Insert to put the recognized math into your wordprocessing or computational program.
Note
 Math Input Panel can only insert math into programs that support Mathematical Markup Language (MathML).

To make corrections
If your handwritten math is misrecognized, you can correct it either by selecting an alternate or by rewriting some of the expression. Here's how to correct an expression:
 Hold down the pen button (or perform another rightclick equivalent) and draw a circle around the part of the expression that was misrecognized. To select an individual symbol, perform a rightclick equivalent while tapping the symbol.–or–Tap the Select and Correct button, and then tap the symbol or draw a circle to select the part of the expression that was misrecognized.
 Tap an alternate from the list.If what you wrote isn't on the list of alternates, try rewriting the part of the expression that you selected.
 Tap Insert to insert the recognized math into the active program.If you tapped Select and Correct but want to continue writing in Math Input Panel, tap Write to continue writing.
Tip
 It's more likely that your math expression will be recognized correctly if you complete the whole expression before making any corrections. (The more of the expression that you write, the better the chance that it will be recognized correctly.)
To use the History menu
With the History menu, you can use an expression that you've already written as the baseline for a new expression. This is useful when you need to write similar expressions several times in a row—for example, when working out a mathematical proof. To do this, tap History, and then tap the expression that you want to use. Your handwritten expression appears in the writing area, where you can make changes. After you make changes, the expression is recognized again, and you can insert it into a document, presentation, or computational program.
To convert handwritten math from your notes
If you use a notetaking program such as Windows Journal to take handwritten notes on a Tablet PC, you can convert the math from your notes so that you can use it in a wordprocessing or computational program. To convert notes from Journal, do the following:
 Tap to open Windows Journal.
 Open your math notes and the program that you want to insert the recognized math into.
 In Journal, use the selection tool to select the expression that you want to convert.
 Tap to open Math Input Panel
 Drag the selected math expression from Journal into Math Input Panel, and then make any necessary corrections.
 In the program where you want to put the recognized math expression, tap Insert.
