Mathematical signs difficulty in teaching learning at the level of a foreign language

This study sought to analyze the difficulties presented in mathematical learning if it has relation to the lack of meaning of mathematical signs. The study had qualitative exploratory bibliographical focus in cury, Vygotsky, D'Ambrosio, Struik and others to identify the meaning of the signs and the importance to the understanding of the sentences that are part of every mathematical practice. The data collection and observation (Test-re-test) to a group of 30 students of the 3rd year of high school of Santos Dumont State College. It can be verified that the students' doubts regarding the meaning of simple theorems are related to contextualization of the historical moment and the motivation for the creation of a certain sign, the construction of meaning as real and effective. However, the presentation of the theorems needs to be modified and deepened for the construction of new ones for the improvement of the teaching of mathematics
