How to say simple math operations???
Hello everyone! I need to know which are the most common (just how teachers say at school) ways to say the following math expressions in english:
3x4=12 (is it 3 per 4?? or i can say 3 dot 4?
4^2=16
25/5=5 (i think this is 25 over 5)

By the way, i have a question related with classes and exams:

A student: - Takes a class??
- Takes or give an exam??

A professor: - Give sa class??
- Takes an exam??

Which are the most common and correct ways to say that?

Thank you so much!

Answer

These would be said like this:

3 times 4 equals 12
4 squared = 16 (for 4 x 4.  If you had 4 x 4 x 4 this would be 4 cubed)
25 divided by 5 = 5

A student takes a class and takes and exam.
A professor gives an exam.  You wouldn't normally say that a professor gives a class, you probably would say that they teach a class.
