The main purpose of this study was to determine differences in the numerical competence of students in terms of gender and various difficulties. The case study research was carried out on 91 students of Al Munawwariyyah Vocational School, Kab. Malang. The t test results showed that there were no differences in the numerical ability of boy and girl students. Some difficulties experienced by students in solving numerical problems include comparing two data from diagrams 54.9%, analyzing table data 61.6%, evaluating values on questions based on the table reference 63.8%, and comparing two graphs with the same function 39.6%. It is recommended to do more mature debriefing for students to prepare for the actual numeracy test in the coming year.","PeriodicalId":440747,"journal":{"name":"Jurnal Pendidikan Matematika Universitas Lampung","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129047498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is a qualitative descriptive study. This study aims to describe the analysis of student difficulties in arithmetic material on Social Arithmetic without any prior treatment. This research was conducted at one of the junior high schools in Soreang. The subjects of this study the sample in this study was taken randomly, were 8 junior high school students, 4 female students, and 4 male students. Based on the research result, the average score for male students and female students have almost the same ability ie 56 and 53.
