Note: Within a priority level, EOS evaluates functions from left to right. Calculations
within parentheses are evaluated first.

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
2p, 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
1à2X as (1à2)…X, while the TI-82
evaluates
1à2X as 1à(2…X) (Chapter 2).

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.
