Why Mental Arithmetic Counts: Brain Activation during Single Digit Arithmetic Predicts High School M
source: http://www.jneurosci.org/content/33/1/156.full#ref-13 "Do individual differences in the brain mechanisms for arithmetic underlie variability in high school mathematical competence?" ... "These data reveal that the relative engagement of brain mechanisms associated with procedural versus memory-based calculation of single-digit arithmetic problems is related to high school level mathematical competence, highlighting the fundamental role that mental arithmetic fluency p
