New research indicates that our brains are not hardwired for mathematics and most often the differences in skills are due to variations in practice.
Mathematical ability is not congenital or passed on from generation to generations although general intelligence is inherited. Experts have noticed that children who come from families where Mathematics was taught before they started school eventually performed better than others. Often major stakeholders in the educational system, the teachers and parents tend to propagate the myth that some children are math oriented while others are not.
Researchers have concluded that mathematics skills are acquired through hard work and practice. Cultures that reward such hard work tend to have people who have better mastery over the subject.
