My teacher is highly illogical. What do I do?

Let it be. My geometry teacher was the EXACT same way all year. He would ramble about nonsensical things and limit us to 2 questions a day. Asking to go to the bathroom or to get a book counted as a question. He would mess up his math and when someone would correct him, he would start yelling about how we were all disrespectful and that we should grow up because we were "young adults now". He also gave us 2 days to complete 8o page workbooks on lessons he never taught to us. Tons of kids complained and even tried to do something about him themselves, but nothing ever worked. The best thing to do is just sit back and try to ignore it. If you have another teacher you could tell about the ridiculous antics of this one, perhaps they could do something, but most teachers won't. I just wish you good luck :)
