Add and edit TeX

1. Open the Simple Editor so that the item you want to edit appears in the Edit Item window.
2. Identify the box where you want to add the expression in TeX (for mathematical or other expressions) or ChemTeX (for chemical expressions).

3. The way you enter TeX or ChemTeX code depends on its location in the Mastering item.

   • To enter TeX in answers: Enter TeX or ChemTeX code directly into the answer boxes for correct answers and for any wrong answer boxes matched to wrong-answer feedback. The TeX symbol or expression renders in the answer box, without the need to preview in Standard View.
   • To enter or edit TeX in all other part text boxes: Select TeX from either the editing toolbar or the editing pop-up menu (right-click on Windows or Control-click on Mac OS).

For a complete listing of TeX codes, see the TeX cookbook. If you use the cookbook, be aware of the following:

• Do not include $ symbols shown in the cookbook. For example, the cookbook shows, $\acute x$. In Mastering, enter \acute x instead.
• Mastering supports most codes shown, but not all of them.
• The cookbook is created and maintained by a third party, not by Pearson.
