The students in secondary school have difficulties making the transition from arithmetic to algebra. In order to obtain the students approach while solving the problem, the students are given a mathematical problem that can be solved by using arithmetic or algebraic. This study is implemented in class grade 7, and they have learnt the introduction of algebra. This research was using a qualitative method with description design. Six students who are a participant in this study have excellent communication and give different strategies while solving the problems. The students are given a mathematical test problem, and then the students are interviewed based on their answer sheet in the test in order to get in-depth information from their strategies. From the result of students are given, we acquire that the arithmetical approach is dominated in their strategy to solve the problem. Many of the students do not realize the using of the quantities of the unknown in that problem. Arithmetic is the approach that accomplished to coverage the students to solve the problem and the students just do numbers and operation, and focus in numeric answer.

Abstract
The absence of empirical understanding of the understudies is the product of less certainly applicable learning frameworks. Quantum Showing depending upon hypnoteching is a finding that is focused on the advancement of understudies of scientific understanding because the information can be explained by means of this model in an effective and competent manner and also because the structures of hypnoteching are anxious to learn while research. This thesis is an exploratory analysis. There are 50 semester understudies from ESTE in this study which have been haphazardly selected. A Quantum Display class is given based on hypnoteaching (QTH), and standard training (OL) is given in a control class. The methods used are: study, interpretation sheet and meeting guide. Knowledge analysis techniques in this study use t-test. The consequence of this research is that QTH testing has a better theoretical perception than OL analysis. Because of the degree of early (large, medium and small) numerical ability, medium and low capacities understudies have seen major differences, but not for high capability understudies. In view of the reaction that occurred during the study, understudies with QTH displayed a movement and stronger ability than OL.
