WHY?
Operations are important, because if you can't work at stores, restaurants, or be an engineer. If you want to do any of those things you have to know operations. Operations are always good. If you don’t know how to add you can't work at a store. If you also want to be a teacher, you have to understand these operations.
If teachers can’t explain how to do operations to their student, the student will never learn how to do these operations. That would not turn out very well. When you know these operations you can be anything you want. If you want to be a scientist you have to use operations.
If you want to be a doctor you have to know how to do operations to do operations on a human body. If you want to be a chef you need to know how to add fractions. Which you have to know how to add before you can add fractions. If the two bottom numbers in the fraction the bottom number will never change.
