MRIs show different brain activity patterns for kids with math learning disabilities When kids with math learning disabilities solve a math problem with number symbols, they approach and process it differently than typical kids. But differences disappear when numbers are shown as dots. Matt Chinworth Some kids struggle with math. Now, scientists have pinpointed some of the specific thinking processes and brain regions that might explain why math is a little harder for some than others. When given simple math problems, kids with math learning disabilities in a new study were less cautious about giving their answers and did not slow down after making errors compared with kids with typical math skills. But these differences disappeared when those same kids were given problems with dots to represent numbers instead of Arabic number symbols, researchers report February 9 in the Journal of Neuroscience. The idea that number symbols can be a challenge is not new. “There’s a very consistent observation that it’s the symbolic p
