When working on assignments in the system, you have a choice of two modes for entering answers to math questions.
The system default mode is Text Mode, which operates using syntax similar to a graphing calculator, combined with a Preview option, which allows you to see what your expression looks like when presented as typeset mathematics.
The alternative is Symbol Mode, in which you enter formulas in a WYSIWYG editing window, pick algebraic symbols and operators from a palette, and see your expressions appear in standard mathematical layout as you type.
The system allows you to toggle Math Entry Modes as often as you want, depending on the requirements of the question and your personal preferences. Each time you change the style of math entry, the system remembers your responses on previous questions, and automatically translates them for you. If you move to a previous question (where you have already entered an answer), your response is displayed in the current editor mode.
You might notice that expressions converted by the system from Symbol Mode to Text Mode appear to have numerous parentheses inserted. This is normal, and is caused by the very explicit method of conversion from symbolic syntax to text that is required to make certain your symbolic expressions are accurately translated. It does not affect the way the mathematics in your answer are interpreted by the system, or the correctness of your responses when graded.
If you change Math Entry Modes using this dialog box while you are responding to a question, your change takes effect after you move to the next question in your assignment. If you want to work with the current question using the alternate math entry mode, use Change Math Entry Mode to select the preferred style of math entry.
Return to your question, and use the system's 
and 
buttons to scroll forward and then back to your question.
This forces the system to reload the question using your preferred style
of entry.
Important: Do not to use the browser Back or Next buttons. You must use the Maple T.A. internal navigation controls to implement these changes. See Navigating Assignments.
