Or there's only perceived ambiguity by people who do understand how maths problems are supposed to be written?
As jhawkkw, who teaches maths at college level, says in his post above:

The ambiguity is caused because maths problems are not usually written in one typed line as the OP provided. That is more akin to a line of computer code, and the way a computer interprets a line of code is not the same as the way a hand written maths equation is usually solved. But to complicate matters, a line of code would not usually have the 2 immediately in front of the parenthesis without an asterisk * to indicate multiplication. The problem 6÷2(2+1) = ?
is not a syntax you would come across either in maths or programming. In maths, the 6 would be drawn over the 2, and in code there would be an asterisk present.
