This is probably one of the hardest chapters I have learned in Math 10. It is complicated and to be honest, at first I did not like it at all. But once you manage to understand the problem more carefully and know how to use the formulas, things will be easier and hopefully, you will like it more.
Now, my favourite part in solving a math problem, obviously, is when I actually solve it and get the right answer. Because it gives me a sense of improvement, accomplishment and eventually, it makes me feel more confident and interested in Math. Especially when it is a hard one which I was not able to solve it before. That is why this chapter is my favourite and my most challenging one at the same time.
