GMAT Prep 1: Symbol issue

The problem with this question is that we are asked if LHS=RHS.
(1) is definitely sufficient. with either + or *, we get a firm answer YES.

(2) the only possible operation is division.
And with division, we get a firm answer to the question- NO.

aren't both the statements enough to answer the question asked?

i hope the the problem asks is @=(+), or (*), @ is a substitute for triangle in original version
(1)3@2>3 possible only for (+) or (*) suff
(2) 3@1=3 also possible for division 3/1=3 and *multiplication
multiplication will give us yes answer (6*2)*4=6*(2*4) but division will not
6/2=3. 3/4
2/4=1/2. 0,5/6=1/12. 3/4 doe not equal 1/12 so 2 st insuff
