The process of subtracting one number from another is known as subtraction.
Given that, there are a total of 150 students out of which 90 were taking algebra and 30 were taking biology.
The remaining students are:
150 - 90 - 30
= 30
Now, the remaining 30 students may take both subjects or neither.
Therefore, the least number of students who could have been taking both courses is 0.
The greatestnumber of students who could be taking both courses is 30.
The greatestnumber of students who could have been taking neither course is 30.
