Dyscalculia is a learning difficulty that affects an individual's ability to understand and work with numbers. People with dyscalculia have difficulties understanding the relationships between numbers and computing them. For many children and adults alike, dyscalculia makes even the simplest calculations seem overwhelming, resulting in frustration, anxiety, and a reluctance to engage with anything numerical even though their intelligence is often preserved. People with dyscalculia are often competent in other learning areas, but when it comes to mathematics, they struggle with basic concepts that others find easy.
