Irrational and imaginary numbers are because of squares and cubes and higher dimensions. Since you have a three d world these numbers exists. That's why knowing about surds is very important. They describe the functional aspects of a structure. Usually when you make cocacola and want to remember the formula it is stored in terms of surds and imaginary equations. Nobody pays because they are factory products. Some people even remember names of chemical engineering products and MA. Machine architecture. Mistakes are necessary in any contention. Whether law abiding.
