I try to be patient but ... a major reason we teach geometry is it's the easiest way to really understand the concept of similarity, ratio and proportion.
You know, the main thing you need to get to "do taxes" ... take a percentage.
I often forget that there are many people who do percentages as algorithms and have no intuitive sense of the difference between 2% and 0.02%
I've seen students show up in calculus who didn't really understand fractions OFTEN. And we must fix that first.
