When I was 9 years old, I finished learning math in the next semester of grade five and the last semester of grade six in four days. Super simple! Both the first and second grades of primary school learn to add, subtract, multiply and divide. /kloc-people aged 0/8 should know, right? So don't look. Suppose you start studying in the third grade of primary school, and the content of a year is assumed to be four days. If you are 18 years old, your intelligence should be better than when I was 9 years old. Get primary school math done in half a month at most. Junior high school math may still be a little difficult. If you don't require the level of the senior high school entrance examination, it is absolutely more than enough to read the content for three years in two months, but only if you spend at least more time reading math books every day. It's hard to say if it's two days of fishing and three days of drying the net. High school math is completely useless, don't look at it ~

If you can really take the time of everyone to keep studying, one month should be no problem. But math is boring, and I'm afraid I can't stick to it. Moreover, primary schools are basically very basic things, and you don't need to think at all. I'm afraid junior high school is a little more difficult.
