Math Dyslexia?

Dyslexia is characterized by decoding, encoding, memory and processing problems with letters, words and numbers. Dyscalculia often only affects the decoding and encoding, memory and processing of numbers. Researchers and authors commonly use the term "math dyslexia" to describe dyscalculia as being "like dyslexia but in math." Dyslexia can result in the same types of errors as dyscalculia, so it is important not to disregard the methods and successes of strategies for mastering mathematics by dyslexics. Some books on "math dyslexia" and "math for dyslexics" appear below. 

It should be noted that dyslexics often are gifted in visual-spatial abilities, whereas dyscalculics are usually limited in tasks involving visual-spatial memory, orientation, and manipulation. (Renee M. Newman)
