The current estimations suggest that about 5-6% of average to the superior intelligence children will have a real deficit in doing maths. Dyscalculia seems to be particularly found in dyslexics around 40% of the people who struggles with reading difficulties also having difficulties in learning maths and the remaining 60%have no problems than normal. It was found already that there is link between dyslexia and math learning difficulties although the latter can occur alone.

It is worth noting that learning about numbers is different from learning to read in an important way. We are born with basic numerical abilities. Infants, even in the first week of life, are sensitive to changes in the number of things they are looking at. We know this because they will look longer at a display when we change the number of things, but often will not when we change one of the things but keep the same number. Babies also seem to be able to do very simple arithmetic. If the baby sees a doll place behind a screen, and then another doll placed behind it, it can be shown that the baby expects there to be two dolls (1 + 1) when the screen is removed. Babies look longer at things they don't expect, and will look longer at one doll or three dolls in this situation. So there is evidence of an innate capacity for numbers. One hypothesis to explain dyscalculia is a lack this innate capacity.

However we don't have a specialised capacity in reading by birth. Reading is a complex skill made up of various brain systems set up automatically to do the other tasks like language recognising visual patterns, sequencing, and so on. And some of these used to learn maths in school and deficits in them may also affect learning in mathematics.

What we need urgently is a way of diagnosing dyscalculia, and separating it from all the other causes of maths problems, including inappropriate teaching. Once we can identify these children reliably, we can begin systematic research on how best to help them. Charles was not diagnosed as dyscalculic until he came into our lab, and, like many other dyscalculics, felt himself first to be incredibly stupid for not being able to do what all his friends could do easily. This was not good for his self-esteem, of course. After that he came to realise that there was something wrong, but he was completely immersed in the dark as what it could be. Better for his self-esteem, but of little practical help. We don't know there are how many cases like Charles, but we are slowly reaching there. Difference between dyscalculic and ordinary people in arithmetic calculations;Ordinary people;For suppose if there is a four dots or four things on a screener the ordinary people(without dyslexia) can identify the things which is on the screener and they can give instant reply with respect to the situation. So therefore the normal people can react very quickly and they can respond very quickly comparing to the dyslexic people.
