I was wondering if you all could tell me where to find these types of problems. I have checked out the sites that is listed here, but none of them have I & O questions on them. I have missed I & O problems on the last two tests, and they are going to be on the final. I know they are simple but I am doing something wrong. I asked my teacher to explain where I went wrong, and she basically said to figure it out on my own. These problems are not covered in our math book at all. So I am at a lost. If no one has any ideas, can you post me an I & O question with the answer to see if I can figure it out. I would appreciate all the help I can get. I want to do good on this final, which is next Thursday. Thanks.
