TI-83 Plus Operating the TI-83 Plus Silver Edition 48
Note:
Within a priority level, EOS evaluates functions from left to right.
Calculations within parentheses are evaluated first.
Implied Multiplication
The TI-83 Plus recognizes implied multiplication, so you need not press
¯
to express multiplication in all cases. For example, the TI-83 Plus
interprets
2
p
,
4sin(46)
,
5(1+2)
, and
(2
ä
5)7
as implied multiplication.
Note:
TI-83 Plus implied multiplication rules, although like theTI
.
83, differ from
those of the TI
.
82. For example, the TI-83 Plus evaluates
1
à
2X
as
(1
à
2)
ä
X
,
while the TI
.
82 evaluates
1
à
2X
as
1/(2
ä
X)
(Chapter 2).
Parentheses
All calculations inside a pair of parentheses are completed first. For
example, in the expression
4(1+2)
, EOS first evaluates the portion inside
the parentheses,
1+2
, and then multiplies the answer,
3
, by
4
.
You can omit the close parenthesis (
)
) at the end of an expression. All
open parenthetical elements are closed automatically at the end of an
expression. This is also true for open parenthetical elements that
precede the store or display-conversion instructions.
