• MISTAKES IN H.C.F. AND L.C.M. OF ALGEBRAIC EXPRESSION

Abstract

In this paper, three problems concerning conceptual and operational mistakes are generally done by the learners in dealing with ‘H.C.F. (Highest Common Factor) and L.C.M. (Least Common Multiple) of algebraic expression’ and their proofs/solutions & explanation of the proofs/solutions of mistakes have been presented. This study has been done through ‘text book scanning’, ‘class room interaction’, ‘answer scripts of achievement test’ and ‘experts’ opinions’. This study will help the learners to understand important mathematical concept of ‘H.C.F. and L.C.M. of algebraic expression’ as well as entire teaching learning process of mathematics.
