The Science: Remember the Numbers Game

Digit span, a measure of working memory capacity, significantly influences math skills. It pertains to the number of digits one can recall in order after a single presentation.

Working memory is integral to mathematical tasks. Solving multi-step arithmetic problems, for instance, involves remembering intermediate results, a game that's easier with a larger working memory capacity. Understanding new mathematical concepts also requires robust working memory to hold multiple pieces of information simultaneously.

Beyond learning new concepts and arithmetic, digit span is crucial for mathematical problem-solving. As many math problems require active mental manipulation of information, a larger digit span can advantage individuals in complex mathematical problem-solving.

Research indicates that digit span can predict mathematical performance, with individuals with larger digit spans often performing better in math. The digit span game can also hint at potential learning difficulties, like dyscalculia or ADHD, which can affect math performance.

Number Memory & The Brain

The dorsolateral prefrontal cortex (DLPFC) plays a crucial role in working memory and numerical cognition.

The DLPFC is responsible for the active maintenance and manipulation of information over short periods of time. It's particularly involved in tasks that require complex, goal directed thought processes, such as reasoning, decision making, and problem-solving.

As for numerical cognition, the DLPFC contributes to tasks that require the manipulation of numerical information in working memory. This includes mental arithmetic and tasks that require keeping track of numbers and performing operations on them.

In essence, when you're performing calculations in your head, the DLPFC is heavily involved in managing the numbers and carrying out the computations.
