  1. The first lecture on mathematics Every future engineer is taught to write the sum of two rational numbers in the following simple form: However, this form is bad due to its banality and makes the lack of education evident.

  2. At the first year one studies that and next and of course everybody knows that

  3. Then the expression can be simplified and you will have to admit that it looks much more understandable and scientific.

  4. Of course it is clear that and also

  5. From this it follows that But this expression can be written even simpler

  6. It is necessary to add that Also the next expression needs no explanation (for a one-dimensional case)

  7. Then considering that and we deduce that

  8. Using the previous expressions we obtain the elegant and simple expression well understandable and easily digestible at the same time for everybody At this moment it becomes clear that this equation is more intelligible than

  9. One can present an infinite number of other possible notations of the expression Good luck!!! Natko‘s Translation
