M
value
EOS™ rules (Chapter 1) determine when negation is evaluated. For example, L4
2
returns a
negative number, because squaring is evaluated before negation. Use parentheses to square a
negated number, as in
(L4)
2
.
Note: On the TI-84 Plus, the negation symbol (M) is shorter and higher than the subtraction sign (N),
which is displayed when you press
¹.
Pi
p (Pi, y B) is stored as a constant in the TI-84 Plus. In calculations, the TI-84 Plus uses
3.1415926535898 for p.
