This paper reports on the discovery of misleading procedure adopted at many places of the traditional resources regarding the mathematical handling of physical quantities. From an extensive literature search, it has been detected that in solving numerical problems based on the mathematical statement of a law in physics or a physical equation, the explicit identity of the symbol of a physical quantity remaining present in the relevant equation, has not at all been considered. Only the numerical value of the symbol representing a physical quantity has been given top priority during the substitution procedure there by totally ignoring simultaneous substitution of the unit of the physical quantity along with its numerical value. With a view to getting rid of such misleading procedure, emphasis has been given on retaining the explicit identity of the symbol of physical quantity (viz. physical quantity = numerical value × unit) at all places of the traditional literature to enhance the teaching learning process in respect of mathematical handling of physical quantities while dealing with numerical problems based on mathematical equations involving symbols of physical quantities.
