MoboMath needs to understand your handwriting in order to return accurate results, but handwriting can often be ambiguous or unclear. This is particularly true if you have poor handwriting or are a messy writer.
If your handwriting isn't being recognized correctly, you can improve your results by following these guidelines.
Write clearly. Poorly formed characters are easily misinterpreted.
Don't connect characters, and use printed rather than cursive letterforms.
Write in as straight a line as possible across the screen, not on a noticeable slant.
Leave adequate space between characters, and don't compress expressions so that elements overlap. If you are running out of space to write in a window, widen the window and then complete your expression.
Write expressions in a natural order, and don't back up to change or add to existing characters. For example, writing "a-b" and then adding a stroke to change the - to a + won't work.
Write parenthesized expressions like "(a+b)" in any one of four commonly used orders – "(a+b)", "()a+b", "a+b()", or "a+b)(" – in all cases resulting in an expression that looks like (a+b).
Keep your expressions well separated. If you are editing or adding more characters to a region, write close to the existing expression. To create a new expression, write well away from any existing regions.
Only add characters to one expression or region at a time. This restriction applies to both new expressions and existing regions.
Remember that you can only perform most editing operations on formatted math expressions, not handwritten ones.
Be sure to write valid math expressions. MoboMath only recognizes meaningful math input.
