Abstract

This research is descriptive research using qualitative approach. This study aims to analyze the types of mistakes made by students in solving linear programming problems based on Newman's theory, in the grade XI students of PGRI Lawang High School. Research subjects taken 6 people from 22 students of class XI MIA. From the research conducted, the conclusions obtained are: (1) 16.7% of students experienced a reading error that can not mean the meaning of the word in the matter.

(5) As for the errors of writing answers made by students as much as 55.6% of students can not make conclusions from the answers obtained.
