Problem-solving is an integral part of the process of learning mathematics in schools that cannot be separated in daily life situations. One of the mathematical material that is found in a daily life situation is a discount. Shopping centers often give double discounts to their customers so the buyers are interested in shopping. A double discount is one of the materials taught in social arithmetic and is an interesting topic to be studied. But the study rarely discusses giving double discounts to high school students. So the purpose of this study is to describe the errors of high school students in solving the problem of double discounts. 122 high school students in the Surabaya, Sidoarjo and Gresik regions participated in the study to solve a double discount problem. Researchers collect student answers to be grouped and analyzed based on the errors they made. The results indicate there are four errors made by students in solving the double discount problem, that is (1) misinterpretation of the problem; (2) errors using discount principles; (3) operating errors, and (4) errors giving final answers. Teachers need to create a learning environment that habituates students to express their interpretations of problems to get appropriate solutions.
