Operation Manual

Figure 268: Context menu in Formula Editor
Note
The Elements window and the context menu contain only the most common
commands that are used in formulas. For some seldom-used commands, you must
always enter the command using the markup language. For a complete list of
commands, see the Math Guide.
Markup language
Markup language is entered directly into the Formula Editor. For example, typing the markup
language 5 times 4 into the Formula Editor creates the simple formula
5×4
. If you are
experienced in using markup language, it can be the quickest way to enter a formula. Table 5
shows some examples of using markup language to enter commands. For a full list of commands
that can be used in the Formula Editor, see the Math Guide.

Greek characters
Using markup language
Greek characters are commonly used in formulas, but Greek characters cannot be entered into a
formula using the Elements window or the context menu. Use the English names of Greek
characters in markup language when entering Greek characters into a formula. See Appendix A,
