Learning mathematics can make us do arithmetic better. For example, if you go to the market to buy food in the future, the boss will give you change. You have to calculate how much the boss should give you. Because I am not good at math, I have a deep understanding of this matter. Sometimes I have to study math hard. If the level is higher, mathematics is also related to science and technology. Some computers, even the 4G we are using now and the 5G coming soon, will use mathematics.
