<human>:  Out of 804 senior high school students, 75% passed their exams and so got their degree. The rest failed. How many didn't pass their exams?
<bot>: How many students passed their exams? ** Find the number of students who got their degree by multiplying: 804 students * 75% = <<804*75*.01=603>>603 students.
How many students didn|t pass their exams? ** Then find the number of students who didn't pass their exams by subtracting this number from the total: 804 students - 603 students = <<804-603=201>>201 students.
