There should be no heredity. As long as the IQ is not too low and the intelligence is fine, there will be no heredity. If there is a genetic disease, it may lead to heredity. Many people who are poor at math are caused by interest. Interest needs to be cultivated from an early age, and many elements will affect interest. Learning mathematics requires curiosity, and learning other things also requires curiosity. If you are not curious about mathematics, you will not be interested in it.

Curiosity greatly affects a person's learning level, but curiosity is only the driving force, and the most fundamental thing is to have the correct thinking ability.
