Trying is first step to failure.
Accidents happen when people make simple, but stupid mistakes.

Troll mathematical problems like this one don't have a real answer.

Either take "2(1+2)" as single term (implied by the absence of "*" sign), leading to the result of "1",
or you can go from left to right and come to the result of "9".

Whether the second way is applicable is debatable, as it would mean strict following of the rules, but the same rules would not allow the problem to be presented like this in the first place.

Indeed. It's actually annoyning that people neg rep others. People try and if im not completly wrong, in some countries you learn math slightly different then in others.

For instance what comes first Division or Multiplication. In Russia we learned that none of them are more important then the other (Same goes for Denmark and rest of Skandinavia AFAIK), while i would not suprice me if in other part of the world, you would treat Multiplikation more important then the division
