Abstract :This study investigates multi-representations raised by prospective teachers in expressing algebra. Through a case study approach, as many as 112 prospective mathematics education teachers from Universitas Negeri Malang of Indonesia participated in this research. researchers use test, interview and research sheet instruments as data collection tools. Then an analysis is carried out so that the following categories are obtained: subjects that symbolically express algebra, pictorial, and geometric. The results obtained that some subjects express symbolically algebra (83 of 112 subjects), while some subjects expressed pictorially (17 of 112 subjects), and geometrically (12 of 112 subjects). The research findings show that there are three forms of representation raised by the subject in expressing algebra, namely the representation of algebraic symbols, image representations, and geometric representations. Most of the participants produced algebraic symbolic representations and some of them experienced obstacles in producing pictorial representations and geometric representations, also researcher found similar patterns in producing geometric representation namely, perception, appearance, strategy, and re-examination. Researchers recommend geometric representations for further research because they tend to be done by subjects with high mathematical abilities and rarely found research that produces geometrical representations when solving algebraic problems.
