At a school called McCormank, there was a certain 5th grade teacher who was notorious for making mistakes. In math class reading, and homeroom. But, whenever she would make a mistake, she'd deny it and say, "I never make mistakes." Now this certain year, the teacher was making an unusually large number of mistakes. Over the year, the teacher made 578 mistakes in math, 455 in reading, and 9,009 in homeroom. If the teacher kept this up for 9 years, how many total mistakes whould the teacher have made???
