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.
