26 Evaluating Expressions
Entering an Expression
To create an expression, you enter numbers, variables, and functions using the
keyboard and menus. An expression is evaluated when you press Í, regardless of
the cursor location. The entire expression is evaluated according to EOS™ rules, and the
answer is displayed according to the mode setting for Answer.
Note: Most TI-84PlusCE functions and operations are symbols comprising several
characters. You must enter the symbol from the keyboard or a menu; do not spell it
out. For example, to calculate the log of 45, you must press « 45. Do not enter the
letters L, O, and G. If you enter LOG, the TI-84PlusCE interprets the entry as implied
multiplication of the variables L, O, and G.
