This research aims to know the reality of using e-learning strategy in improving the learning of mathematics in university education, and to know the moral differences between the variables, the researcher used the descriptive and analytical method with the questionnaire tool consisting of (30) paragraphs distributed in the fields of education, learning and evaluation, addressed to a random sample of (110) students and the Mathematics teaching staff of (34) members of Prince Sattam bin Abd Al-Aziz University in Wadi Al-Dawasir at tow Colleges (Arts, Sciences and Engineering) for the first semester of the academic year 2021. After collecting and analyzing data statistically, the researcher came up with the following findings: The most important ones are: the existence of good efficiency in using e-learning strategies in teaching Mathematics , learning and evaluation process, especially in the focus of education, the presence of obstacles in the way of the use of e-learning strategies in learning the university student, especially weak internet, and the absence of statistically significant differences in the efficiency of using strategies of e-learning in learning Mathematics for gender , and for the cumulative academic rate, there is an urgent need for training faculty members and students to improve the use of e-learning strategies in teaching and learning Mathematics, especially when it comes to developing. The research came up with a set of recommendations the most important of which is increasing community awareness to calling for: action to spread the culture of using e-learning in teaching in universities, addressing the obstacles facing the use of e-learning strategies, draw attention to training students and members of Mathematics teaching staff on what is new in the field of educational technologies.
