PulsingFlower- I see it as ignorance. The concept isn’t difficult. The issue is that many people have never come across the concept in a way that they remember. This shows a lack of schooling (or an awful memory, which perhaps might be pitiful, but it doesn’t seem that you were thinking along those lines), and lack of any real life experiences that require simple math rules. Many people have no need for such knowledge and live complete lives without it. I don’t see inherent value in knowing simple math rules, thus I have no pity for those who were never exposed to them.
