M
value
EOS™ rules (Chapter 1) determine when negation is evaluated. For example,
L
4
2
returns a
negative number, because squaring is evaluated before negation. Use parentheses to square a
negated number, as in
(
L
4)
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
