Dyscalculia is a learning disability in math. People with
have trouble with math at many levels. They often struggle with key concepts like bigger vs. smaller. And they can have a hard time doing basic math problems and more abstract math.
Snapshot: What Dyscalculia Is
Dyscalculia is a condition that makes it hard to do math and tasks that involve math. It’s not as well known or as understood as
. But some experts believe it’s just as common. That means an estimated 5 to 10 percent of people might have dyscalculia.
There are different terms for dyscalculia. Mathematics learning disability is one. Mathematics learning disorder is another. Some people call it math dyslexia or number dyslexia. This can be misleading. Dyslexia is a challenge with reading. Dyscalculia is a challenge with math.
People don’t outgrow dyscalculia. Kids who have a hard time with math may continue to struggle with it as adults. But there are strategies that can help them improve math skills and manage the challenges.
Difficulty with math happens at all levels. It can be as hard to learn addition as it is to learn algebra. Basic concepts like quantities can also be a challenge.
That’s why dyscalculia can make it hard to do everyday tasks. Cooking, grocery shopping, and getting places on time all involve these basic math skills, which are known as
Researchers don’t know exactly what causes dyscalculia. But they believe it’s at least partly due to differences in how the brain is structured and how it functions.
Here are two possible causes of dyscalculia:
Genes and heredity: Dyscalculia tends to run in families. Research shows that genetics may also play a part in problems with math.
Brain development: Brain imaging studies have shown some differences between people with and without dyscalculia. The differences have to do with how the brain is structured and how it functions in areas that are linked to learning skills.
Researchers aren’t just looking into what causes dyscalculia. They’re also trying to learn if there are strategies that can help “rewire” the brain to make math easier.

How Dyscalculia Is Diagnosed
The only way to get a diagnosis is through an evaluation. This can happen at any age. Evaluators use different tests for adults than for kids.
Kids can get an evaluation for free at school. There are also specialists who do private evaluations of kids and adults. Private evaluations can be costly. But there are local resources that offer
free or low-cost evaluations.
Evaluators use a set of tests just for dyscalculia. But evaluations also involve testing for other challenges. That’s partly because people with dyscalculia often also struggle in other areas, like reading or
working memory. But evaluations don’t just point out challenges. They also show strengths.
A diagnosis (schools use the word identification) lets kids get supports and services at school. For example, kids might get
special instruction in math. The school might also give
accommodations to make learning math easier.
Adults with dyscalculia may get accommodations at work. The law requires employers to give supports to people with disabilities. That includes people with learning disabilities.
A diagnosis of dyscalculia can sound scary. But many people find it a relief to know that their challenges with math are real. Plus, getting the right supports can help them thrive in school, work, and everyday life.
