In a class of 54 students, 36 are in Algebra class and 32 are in Biology class. Out of all these students, 21 are in both Algebra and Biology classes. Determine the number of students:

25students are not taking any of biology or algebra

Step-by-step explanation:

students taking algebra + students taking biology + both + not taking both = all students

36 + 22+ 21 + not = 54

79 + not = 54

not = 54 - 79 = 25students are not taking any of biology or algebra
