Note: Within a priority level, EOS evaluates functions from left to right. Calculations
within parentheses are evaluated first.
Implied Multiplication Implied Multiplication Implied Multiplication Implied Multiplication
The TI-84 Plus recognizes implied multiplication, so you need not press
¯ to express
multiplication in all cases. For example, the TI-84 Plus interprets 2 p, 4sin(46) , 5(1+2) , and
(2
…
5)7 as implied multiplication.
Note: TI-84 Plus implied multiplication rules, although like the TI-83, differ from those of
the TI-82. For example, the TI-84 Plus evaluates 1 à 2X as (1 à 2) … X , while the TI-82
evaluates 1
à
2X as 1
à
(2
…
X) (Chapter 2).
Parentheses Parentheses Parentheses 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.
