If you say that people who are not good at math have low IQ, then there are many people who are not good at math, but they do well in other subjects. You can say that their IQ is low, so whether math is good or not has little to do with IQ.
People who are not good at math may be because they didn't study hard at the beginning, which led to poor math performance. By the time they finally want to learn, it will be too late. After a long time, they will definitely not want to learn, and their math scores will naturally be worse, so this has a lot to do with learning the day after tomorrow.
We often find that many students are not good at math and excellent in interpersonal skills or other aspects, so we can't generalize, so we should consider them in many aspects. In society, the same is true. Everyone is good at different things in different development fields, and so is learning. It's not that people who are not good at math will have poor IQ.
What are the manifestations of low brain IQ?
In fact, there are many manifestations of low IQ, which we can easily find in our lives. For example, some people are blind and slow to respond to some external things, which we can clearly see. Some people may find it difficult to concentrate on some things, and they may also have ADHD in peacetime, which is obviously different from ordinary people.
And people with low IQ have very poor learning ability. Maybe some knowledge teachers have been teaching for a long time, but they can't learn it. This means that in any case, some people with low IQ may still stay at the level of children. These are obvious manifestations of low IQ.
Most people in our lives are basically not like this, or people around us are basically not people with low IQ, so students should not worry about their poor math, that is, their IQ is low. This idea is obviously incorrect. As long as we study hard, there will always be subjects that we are good at.
