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.
