Technological literacy among high school mathematics teachers is a crucial aspect in realizing creative, interactive, and relevant learning to meet the demands of the 21st century. However, the reality on the ground shows that most mathematics teachers still have limited experience in improving technological literacy, particularly in the use of artificial intelligence (AI) as a learning support medium. This condition has implications for low innovation in the mathematics learning process. This community service activity aims to optimize the use of AI, specifically Generative-AI technology, in supporting mathematics learning in high schools. The target group is members of the High School Mathematics Subject Teachers' Conference (MGMP) throughout Grobogan Regency, Central Java Province, Indonesia. The implementation method includes workshops, interactive discussions, hands-on practice, and mentoring in the development of AI-based mathematics teaching materials, assessments, and learning media. The training materials include an introduction to the basic concepts of Generative-AI, effective prompting techniques, and practice using various AI applications to produce interactive and contextual teaching materials. Evaluation results showed that all training participants agreed or strongly agreed that this activity successfully improved their understanding of the basic concepts of Generative AI and their skills in operating AI applications for mathematics learning. Participants also reported increased confidence in integrating AI technology into their teaching practices, as well as gaining various relevant practical ideas for classroom implementation. High enthusiasm was evident in the 100% commitment of participants who expressed their readiness to implement AI technology in mathematics learning. Thus, this training not only contributed to improving teachers' technological literacy but also became a strategic step in encouraging innovative and adaptive transformation of mathematics learning in the digital era.

Mathematical logic is a branch of science that studies the principles of logical reasoning and how to judge the truth of a statement. This article discusses the role of mathematical logic in everyday life, especially in education, technology, and finance. Mathematical logic has been proven to help improve critical, analytical, and systematic thinking skills, making it easier for individuals to solve various problems more effectively and efficiently. In the world of education, mathematical logic supports the development of rational, argumentative, and problem-solving skills, and is an important foundation in the science and mathematics curriculum. Teachers can leverage this logic to encourage students in building consistent reasoning and logical argumentation. In the field of technology, mathematical logic is the foundation in the development of modern computing systems, such as algorithms, programming, artificial intelligence, and data structures. Without mathematical logic, digital systems such as search engines, software, and applications cannot function optimally. In finance, mathematical logic plays a role in budget strategy, investment decision-making, statistical analysis, and rational risk management. With a good understanding of logic, individuals and institutions can make more wise and measurable financial decisions. Although his contribution is large, there are still many people who do not understand the basic concepts of mathematical logic. This can be overcome through more inclusive education, contextual approaches, and interactive learning based on real problems, both in schools and non-formal environments. This study emphasizes the importance of mathematical logic as a foundation in supporting a more rational, efficient, and structured life in today's modern era. Increasing mathematical logic literacy can be a national strategy to create a society that thinks critically, is competitive, and ready to face global challenges.

This research aims to examine the learning methods and challenges faced by several students when solving mathematics problems regarding number patterns, with an emphasis on analyzing students' thinking processes. This study employs an approach to analyze students' ways of thinking. In this study, a qualitative approach is used with a case study method on a group of junior high school students. Information was collected through observations and analysis of students' work. The findings of the research indicate that students apply various strategies in understanding the material of number patterns, which include memorizing patterns to trying to find their own formulas. However, many students face difficulties in drawing conclusions about patterns and connecting relevant mathematical concepts to everyday life. Common mistakes include errors in recognizing patterns, errors in calculations, and a lack of precision in understanding problems. Analysis of the thinking process shows that some students are still at the concrete operational thinking level, so they need visual aids and real-life examples to better understand patterns. This research emphasizes the need for an approach in teaching that can enhance students' abstract thinking abilities and requires varied practice in determining numerical pattern problems.    

This study aims to analyze the types of student learning difficulties in solving mixed arithmetic operations based on the Newman Error Analysis (NEA) approach. This research uses a descriptive qualitative approach with literature study techniques on national scientific articles published between 2020 and 2025.

Mathematics plays a crucial role in everyday life, as it enhances students' abilities to absorb lessons more effectively and develop rational, critical, logical, analytical, and systematic thinking. This study employs the literature review method, which involves gathering relevant information from various sources to support the research topic. The author collects references from articles and journals using Google Scholar, an open-access database that simplifies the process of locating topic-specific materials. Difficulties faced by students in learning mathematics are not always due to a lack of mathematical knowledge. They may stem from other issues such as memory problems, difficulty in recalling mathematical problems, weak calculation skills, confusion with operational signs, or reversing numbers. Students with learning disabilities may particularly struggle with both mathematical reasoning and basic computation. Furthermore, mathematical learning difficulties are also associated with cognitive challenges, such as solving complex word problems and understanding numerical concepts. These learning difficulties often result from internal and external factors that hinder the brain’s ability to process, analyze, and retain mathematical information effectively.
