Online quoted a math problem hot allegedly 3.4 mil

network
340 million Internet users solving math teachers come to two answers: positive solution of monomial mischief 9

like simple math problems, the answer has caused many users of heated discussions.
reporter in line to see, This question has been called the 1 and 9.
factions clash

think the answer is 1

this part of the users that for as a whole. To 3x an example, from the point of view factor, 3x is not 3 · x,louis vuitton handbags, nor is 3 × x, but rather represents a whole number.
Second, outside directly with the number in parentheses is the coefficient as the content exists within parentheses, rather than exist as a multiplication. This means that the brackets (1 +2) each to be multiplied by 2.
1 + 2) =? who still intend to select 9?
VS

think the answer is 9

but there are users that,mbt shoes sale, according to the mixed addition and subtraction multiplication and division four algorithms inside the brackets should be counted, draw The results for the three and the rest is multiplication and division operations. Algorithms according to the provisions of the peer computing, from left to right calculation.

math teacher analysis

2 (1 +2) is not a single answer to this question type should be 9

the Road Network This morning, Beijing Technology and Business University, Department of Mathematics, Liu said, according to algorithms,nike air max, should be calculated in the formula in brackets, that formula becomes, the same level of operation, the results counted from left to right 9.
Liu analysis, it was the and letters can be seen as a single type. This question is present, but there are no letters, one that should not have individual style.
again, 2 × and 2 () is not a concept, 2 () is not a factor, does not mean it is a whole, is used to sense a kind of multiplication ellipsis, it is not in parentheses where each is multiplied by the number outside the parentheses.
in accordance with the algorithm, that is the first operator in brackets, and similar operations, to be from left to right, the result is 9.
In addition, This question is the latter part of the formula more compact, from the visual senses are likely to be considered on the back,louis vuitton outlet store, there are certain psychological effect.
Liu stressed.
