Fist of all 2(9+3) is NOT always 2*(9+3). Some people/institutions interpret it as 2^(9+3), which would be a completely different number, so the lack of the indication of operation is faulty.

Also, the presentation is laughable. This is how you represent division (for example):

That ÷ symbol is nonexistent after elementary school classes (at least here). So that's another thing that is incredibly faulty.

Finally, the order of operations depends on the countries: here division has priority over multiplication, but it's different depending on the institution/country, so of course it'll have different results.

So, with might be 2 (if you multiply before division), 288 (if you divide before multiplication) or 3/256 (if you use exponential instead of multiplication).

There, happy?
