This paper is concerned with an unambiguous understanding of physical quantities at a basic level where one is to deal with mathematical symbols linked to scientific concepts. To form an unambiguous understanding of physical quantities and their mathematical handling, a revisit has been made to some of the well-known notations/concepts such as: (i) symbols for physical quantities, (ii) quantity calculus, (iii) principle of unit-independence, and (iv) various kinds of physical equations. The fact that prior knowledge about quantity calculus, the principle of unit-independence, and the notations for physical quantities is essential to mathematically handle physical quantities has been emphasized, along with considering the importance of numerical value equations for physical quantities.
