According to Wikipedia:
An expression like 1/2x is interpreted as 1/(2x) by TI-82, but as
(1/2)x by TI-83. While the first interpretation may be expected by
some users, only the latter is in agreement with the standard rules
stated above.

That behavior is available, but you have to ask for it by setting
`calc-multiplication-has-precedence' to nil.
