This paper has investigated on how much understanding of equal sign the 7th grade students have in the process of solving linear equations. The result of investigation are as follows. First, it was shown that most students prefer transposition while solving linear equations. And the fact is that they concentrate on calculating the answer by putting behind the proper expression of equal signs as they use the transposition method. In other words, they have an instrumental understanding of equation that the symbol changes when items on left side are moved to the right side. In the symmetrical expression of equal signs, only about 20.7% of students were shown as expressing properly in all questions while other students were shown as having difficulty in expressing equal signs properly. Second, the students making mistakes could be corrected by interviewing each students. Therefore, it would be necessary to correct mistakes on an individual basis by investigating the learning status of each student. Also, a teaching-learning method to raise the learning habit of being able to solve problems using characteristics of equality and transposition method as well as letting students gain adequate experience on various types of problems would become necessary.
