As noted in help unexpected:

$ calc
C-style arbitrary precision calculator (version 2.15.0.1)
Calc is open software. For license details type:  help copyright

; help unexpected

In particular: calc always evaluates terms from left to right.

12/2 ==> 6 6(3+3) ==> 66 ==> 36

Calc works as documented and by design.

Thanks for the detailed reply. I was trying to give an example of the distributive law - 2(3+3) - but corrected the example quite badly when I saw it thinking of x(1 + 3) as a function with x.
