Dyscalculia involves frequent difficulties with everyday arithmetic tasks like the following:
- Difficulty reading analog clocks
- Difficulty stating which of two numbers is larger
- Inability to comprehend financial planning or budgeting, sometimes even at a basic level; for example, estimating the cost of the items in a shopping basket or balancing a checkbook
- Difficulty with multiplication-tables, and subtraction-tables, addition tables, division tables, mental arithmetic, etc.
- Difficulty with conceptualizing time and judging the passing of time. May be chronically late or early
- Problems with differentiating between left and right
- Inability to visualize mentally
- Difficulty reading musical notation
- Difficulty navigating or mentally “turning” the map to face the current direction rather than the common North=Top usage
- Having particular difficulty mentally estimating the measurement of an object or distance (e.g., whether something is 10 or 20 feet (3 or 6 meters) away).
- Often unable to grasp and remember mathematical concepts, rules, formulae, and sequences
- Inability to concentrate on mentally intensive tasks
- Low latent inhibition, i.e. over-sensitivity to noise, smell, light and the inability to tune out, filtering unwanted information or impressions. Might have a well-developed sense of imagination due to this (possibly as cognitive compensation to mathematical–numeric deficits)
- Mistaken recollection of names. Poor name/face retrieval. May substitute names beginning with same letter.
