each line. The clues (vertical line and numbers) were progressively eliminated. In a text with no more than 12 lines, the patient had to complete the missing letters (i.e., perform sequential and ordered spatial exploration). Letter cancellation exercises were repeated constantly, and clues to facilitate their execution were included. Time and precision were recorded. In spontaneous writing exercises using lined paper with a thick colored line in the left margin, the patient had to look for the vertical line when finishing each line. Later, the line was eliminated, but the patient had to verbalize (initially aloud and later to herself) and explore to the extreme left before beginning to read the next line. To facilitate the relearning of numbers through dictation, squares were used to place the numbers in space, and the concepts of hierarchy were practiced permanently (units, tens, hundreds, etc.). To provide training in arithmetical operations, she was given in writing additions, subtractions, multiplications, and divisions with digits separated in columns by thick colored lines and the tops of the columns were numbered (from right to left). The patient had to verbalize the arithmetical procedures and, with her right index finger, look for the left margin before she could pass to the next column. Later, the patient herself would write the operations she was dictated. The techniques described previously were proven useful 8 months after the treatment was started. The patient presented significant improvement but in no way a complete recovery." Individuals with acalculia generally live normal lives, unless there are other disabilities or traumatic injuries present that prevent normal living. Details from a case study published in 2003 described the condition of a 55-year-old woman living with acalculia. "In addition to writing and calculation deficits, both spelling and reading had declined. Lapses of memory occurred occasionally. Despite these deficits, daily living activities remained intact". Another case study published in 1990 described the condition and management of a former female accountant who had "suffered a small circumscribed left parietal subdural hematoma in an auto accident." She was able to speak, read, and write normally, but she was unable to perform simple addition past the number ten. The case study reports that the patient also demonstrated "severe finger agnosia, and in fact the finger agnosia appeared to be directly related to her inability to perform calculations." The patient was somewhat able to manage her acalculia by visiting a therapist
