Introduction
The dimensional analysis does not allow physical quantities with different units to be added or subtracted. For example, one cannot add length (unit: meter) to time (unit: second); weight (unit: kg) to amount of substance (unit: mole); and so on and so forth. That is literally the case if you pay attention carefully to all the chemical, mathematical, or physical equations.
