e^( (exponential, yJ) returns the constant e raised to a power. You can use e^( with
real or complex numbers, expressions, and lists.

e (constant, y [e]) is stored as a constant on the TI-84 Plus. Press y [e] to copy e to
the cursor location. In calculations, the TI-84 Plus uses 2.718281828459 for
e.

Negation
M (negation, Ì) returns the negative of
value. You can use M with real or complex
numbers, expressions, lists, and matrices.

value
EOS™ rules (Chapter 1) determine when negation is evaluated. For example, LA
2
returns a negative number, because squaring is evaluated before negation. Use
parentheses to square a negated number, as in
(LA)
