TI-83 Plus Math, Angle, and Test Operations 66
L (Negation)
M (negation, Ì) returns the negative of value. You can use M with real or
complex numbers, expressions, lists, and matrices.
Mvalue
EOS™ rules (Chapter 1) determine when negation is evaluated. For
example, LA2 returns a negative number, because squaring is evaluated
before negation. Use parentheses to square a negated number, as in
(LA)2.
Note: On the TI-83 Plus, the negation symbol (M) is shorter and higher than the
subtraction sign (N), which is displayed when you press ¹.
p (Pi)
p (Pi, y B) is stored as a constant in the TI-83 Plus. In calculations,
the TI-83 Plus uses 3.1415926535898 for p.
