It puts me off a bit when sewing instructors put a "Content Warning: Algebra!!" in their tutorials.
Like yes, if you are doing a circle skirt you need to calculate a circle radius from you waist measurement. And yes, it means you need to divide it by \pi.
And it should be perfectly normal for adults to be able to divide two numbers.
And when you do a 6-panel skirt you need to divide by six. It is not black magic.
I get that it is supposed to be a joke, but is it a good joke then?
