From my point of view, learning mathematics has the following advantages.

First of all, mathematics is very important in the college entrance examination. Studying math carefully can help us get good grades in the exam.

Next, in our life, we use mathematics almost every day. For example, in shopping malls and banks ..... as long as we use money, we must use math. Obviously, mathematics is very important in reality.

Finally, mathematics can also practice our way of thinking and make us smarter.

In a word, mathematics is important.

I hope you are satisfied, it may not be level 1, but you can modify it yourself.
