There were ten students who were just about to take a math exam and needed to be prepared with acalculator.
Five were WISE
Five were FOOLISH
The foolish students did not have a calculator, while the wise students cameprepared with one.
The five foolish students asked their peers if they had a calculator that they could borrow, but unfortunately, they only had a calculator for themselves. They told them to go around the school to see if they could borrow one from other students or teachers.
10 minutes later... they arrived with calculators
Once they all came back to class, they tried to open the door, but it was locked. The exam had already begun before they had returned.
Once the teacher opened the door, she did not allow them to start writing. School rules state that students who arrive late to an exam are refused entry into the examination room and are considered absent.
Due to the unpreparedness of the foolish students, they missed their math exam and received a mark of zero. As a result, they endured the consequences of having their final grade and possible future opportunities negatively affected..
