Rapid technological advances make print communication media begin to be shifted by information media that utilizes computer technology as a means of delivery. Technological developments change the teacher's task from being a teacher to a facilitator who provides convenience in learning. SD Negeri 004 Bangsal Aceh is one of the schools that still applies the mathematics learning process using textbooks so that students do not understand the lesson. Teachers are required to make changes in teaching patterns in the classroom, one of which is with animated videos. This study uses the Multimedia Development Life Cycle (MDLC) method covering concept, design, collecting material, assembly, testing and distribution. The final result of this research is an animated video of mathematics learning about the material of flat shapes. Animated videos are used as an interesting and effective means of information and learning media. Besides that, it can also improve students' understanding and skills in learning mathematics, especially the material of flat shapes

Mathematics is an applicable science and very close to human life, so mathematics is very important to learn from elementary school. However, the mathematics competence of elementary school students in Indonesia is relatively low. One of them is SD IT Cahaya Ummat which is located in Karangjati, Kecamatan Bergas, Kabupaten Semarang, the grade 6 students' average mathematics score is lower than other subjects. So far, learning is still conventional in nature with learning resources in the form of printed books, thus it is necessary to have learning innovations to increase students' interest in learning mathematics.The design of interactive media as a learning aid can be a solution to attract students' attention to be more focused when the teacher explains math material in class. When students feel interested and focused on learning, learning will be more effective so that students' understanding of the material presented by the teacher will also increase.Interactive learning media made with Adobe Flash CS5.5 to combine text, images, sound, and animation will make the application more attractive, so that students are more interested in learning mathematics with statistics material. The results of the validation score obtained from media experts are 34, material experts 39, and users 35, so this learning media product is classified as a very good category, so it is valid to be used.

Matematika secara garis besar dibedakan menjadi dua, yaitu matematika terapan (applied mathematics) dan matematika murni (pure mathematics). Matematika terapan mempunyai pengertian bahwa matematika digunakan diluar matematika. Matematika terapan berperan dan membantu menyelesaikan masalah-masalah di dunia nyata yang akan diselesaikan dalam sistemnya dan memenuhi kebutuhan ilmu-ilmu dalam pengembangannya. Banyak ilmuwan yang mengkaji matematika untuk dapat dimanfaatkan dalam bidang lain. Sedangkan matematika murni berperan sebagai ratu yang mempercantik dirinya melalui rancangan-rancangan definisi, teorema yang terstruktur secara sistematis. Teori Aljabar Linier  merupakan cabang dari matematika terapan. Aljabar Linier mempunyai penerapan pada berbagai bidang ilmu alam dan ilmu sosial serta teknologi khususnya teknologi Informasi dan komunikasi (infokom) yang saat ini sedang berkembang pesat. Ilmu yang dipelajari pada materi Aljabar Linier salah satunya yaitu Sistem Persamaan Linier. Adapun salah satu metode yang dapat digunakan untuk mencari nilai variabel adalah Aturan Cramer
