I feel that I am very stupid, IQ is also low how to do I a small to big math did not pass I also heavy hearted school when the teacher said I want to learn can not learn

Don't put the blame on your own innate stupidity, in fact, everyone's IQ is similar. The success or failure of a person's work does not lie in how much talent God has given you, but in how much sweat you have paid.

The reason you feel your logical thinking skills are not strong is that you have not been able to get a satisfactory performance in the relevant field. And you haven't approached this failure with a proper mindset from the start, only blaming it on a lack of talent. So you use this as an excuse to take it for granted that you can't learn well, and a vicious circle is formed unknowingly from childhood to adulthood.

In fact, what you lack is not much, just a little confidence, a little patience and a little hobby. Many people play poker, mahjong and chess and even study not for some official purpose, only in a kind of interest. As the saying goes, interest is the best teacher. Of course interest can't be forced, but you should at least do these things without thinking of them as too hostile.

Learning math is not difficult, you can even say that learning is not difficult, they are just a collection of knowledge points one by one. You shouldn't feel like you can't make up for dropping a lot of them. As long as you turn from the beginning and get the knowledge points on each page, that's progress. The important thing to note is that mastery is not memorization but understanding, and you have to learn to think about why in order to really understand by example.

And, people don't think too much, parents are good for you, they expect their son to be a dragon, but they prefer you to be happy, don't hold your sadness in your heart, repression will only make people become broken, and make your parents worry more. You should find some ways to change your negative emotions. Everyone carries a different life, a different suffering, but also has a different joy and happiness. Don't take your own shortcomings and compare them with other people's advantages, you always have something better than others. Everyone has.
