One of the underlying problems is visual processing, such as writing a number down incorrectly after looking at it. An example would be seeing the number '05' and then writing down '50'.
Another underlying problem is sequencing, such as trying to work out a math problem that has several operations, such as word problems and algebra.
From resource 3. about learning math skills: "Repetition is very important. Use rhythm or music to help memorize."
My 'Math while Moving' series offers kinesthetic lesson plans for practicing repetitive counting, addition, subtraction and sets.
Here are resources that list many of the possible symptoms, and offer ways to mitigate the affects, including using hand-held calculators.
