The data obtained were then analyzed starting from data reduction, data exposure and conclusion drawing. The results of this study indicate that from the subject of 5 students only 69% of the questions were able to be solved and none of the students were able to solve the problem completely. This happens because the average student has difficulty understanding the purpose of the problem and it is difficult to determine how to solve it.
