摘要：AbstractThe language is based on two essential sides: the semantic side and the syntactic one, but when we talk about the formal language, we associate spontaneously to this, the mathematics and data processing. Therefore, it is noted that the mathematical language does not comprise the semantic side, hence, the handicap of this language. The question which arises here: “can we highlight the semantic property in the mathematical language?”
