Language is a medium through which ideas are expressed and through which communication between people is formed. Learning English plays an important role in the process of learning the size of languages and other things as well. In this regard, the effect of bilingualism on students' math learning is important. Teaching a second language helps students to increase their understanding of the material. Mathematics as one of the main subjects of students is important for progress and success. It also serves as a major tool to improve students' logic. Thinking and cognitive skills in other scientific fields such as physics, statistics and engineering depend on mathematics. Therefore, mathematical skills are a necessary condition for understanding other subjects.

One of the most important critical components of learning mathematics is solving conceptual problems. In fact, the understanding of mathematics is primarily dependent on the concept of the word. Therefore, the influence of bilingualism on math learning cannot be ignored.

Most students who only speak their mother tongue have a harder time learning math. Because their language is different from mathematical language. But bilingual children who are familiar with English learn it more easily by understanding math words 

According to research, success in mathematics depends partly on verbal skills. In multilingual educational environments, learning English helps students improve mathematics. 

Proficiency in mathematics is not just a calculation skill but also depends to some extent on word comprehension abilities. Research shows that performance in mathematics depends on English proficiency. Usually, the content of the mathematics curriculum is often transmitted orally from the teacher to the students. While the teaching and evaluation of this curriculum is done through books and written evaluation, therefore, insufficient mastery of English in mathematics education will inevitably lead to problems in solving mathematical problems. However, the relationship between language and math abilities has become a concern in multicultural and multilingual educational environments that aim to educate a large number of students with immigrant backgrounds and different languages with different fluency. According to the aforementioned relationship between language and math achievement, students who speak their mother tongue have less mastery in math learning.
