Yet the way I was taught, the answer is 9. The way I taught my children and the way they were taught in school, the answer is 9. I still hold to the fact that math is an exact science and a calculation is to be done in the order it is presented. I went to high school over 45 years ago and the way I was taught would give me the answer 9. I do not know what college or professor changed the rules, but I would sure like to see it written down in a current math book.
