NO NO!! I used to say this too, but the 82 and 85 (not the 81) give implied
multiiplication with paraentheses higher priority than square roots and
other calculator defined functions.

Try SQRT4(-4)     The three calculators each give a different answer.

Graph Y=(1/2)X  and Y=1/2(X)           yep! they're different.
