The original version of this article contained an editing error towards the end of section 1. The corrected passage is given below.

Marchini and Papadopoulos (2011) showed that elementary school students could gain from using emphasizing brackets. In their experiment young students (grades 2 and 3 in Italy and Greece) compared simple algebraic expressions, and emphasizing brackets improved the number of correct answers in cases such as, for example, Open image in new window + 4 = 9 and ( Open image in new window + 4) = 9. Brackets can indeed change the way in which expressions are perceived.
