Exponential Exponential Exponential Exponential
e^( (exponential,
y J) returns the constant
e raised to a power. You can use e^( with
real or complex numbers, expressions, and lists.
e^(power)
Constant Constant Constant Constant
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 Negation Negation 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, L A
2
returns a negative number, because squaring is evaluated before negation. Use
parentheses to square a negated number, as in ( L A)
