What concept learned in this course was the easiest for you to grasp? Why do you think it was easy for you? Which was the hardest? What would have made it easier to learn?

The easiest concept to grasp in this math class was the explanation used to determine when to flip the sign in an inequality. Whenever you have to divide or multiply by a negative number the sign in an inequality changes or flips. This is the easiest explanation of when to flip the sign of inequalities; I was never sure when I studied the topic in high school. One of the hardest concepts to grasp was the use of PEMDAS. I never understood why there must be order to solving equations throughout the equation. It was difficult for me to grasp the order, but once I read up on the topic I understood that there must be an order so that regardless of the writing of the equation it will always be solved the same way. It would have been easier to understand if the concept that it is just a certain order to solve math all of the same way was explained.
