Life can be without poetry, but it can't be without poetry; There can be no road in the March, but there must be no steps forward; You can have no experience at work, but you can't study. There can be no flash in life, but there can be no stain. Mathematics learning can't give up basic learning, but choose the number of topics. The following is what I have summarized for you. I hope you will like it.
