Column Addition Challenge WORKSHEET DESCRIPTION
This worksheet is designed to provide some more challenging problems involving the formal column addition method. Section A begins with some straightforward sums, each involving three 3-digit numbers. Section B then asks learners to use only digits from 1 to 9 to make the column addition correct. Section C asks for the digits 0 to 9 to be used to form a question and answer and section D asks for the values of letters replacing digits to be found.
