Abstract
Most assessments conducted across the country indicate that the first stumbling block for many
children is the subtraction operation, followed by division. On looking more closely we see that
the difficulties often arise in subtraction contexts involving double digit or larger numbers. This
difficulty is largely caused by three factors: (i) improper understanding of place values (ii) lack of
understanding of the rationale behind the formal subtraction procedure, (iii) not seeing the
connection between addition facts and subtraction facts
