The results showed that at the step of understanding the problem, student with a choleric personality type are less fluent and detailed in explaining the known and asked information. While student with phlegmatic personality type did not write down the known and asked information on the answer sheet at all due to difficulties when converting the information to mathematical form. All four personality types mention the adequacy of information by looking at what is known and asked information.
