My teacher (let's call him Mr. X) gives an entry task every other day. On this one, he let us use a calculator.

My calculator apparently couldn't handle fractions and exponents so I asked my friend if I could borrow his for a bit. Mr. X sees this and gets mad at me for "not doing what I told you to do." Which was to write down the question in my comp book. Keep in mind that below the question, it said to DISCUSS IT WITH YOUR TABLE PARTER.

I just told Mr. X that I had just opened the book a few seconds ago and was asking my friend about the calculator.

He yells at me stating that me saying "I just opened the book" was disrespectful and rude and that I should never say such things again.

I basically just sat down and shut up for the rest of the class. AITA?
