Hehehe
That's the language of engineering.
Think of how to model a randomly distributed load on a cantilever. Example an earthquake or a dam seepage.
Those designs aren't random, there's a mathematical computation behind it.
Excel is a great tool but has so many shortcomings for engineering applications. As an example, try working Fourier series or Laplace transforms with excel and you won't go far. Or basic things like matrices.
