You still run into problems that require some math discipline and understanding. If you're writing CRUD apps, you need to know what a Cartesian product is or why big O matters. Or how to calculate disk space requirements and transaction times.
The fact is we might use things that have formal definitions without knowing what the definition is, or understanding the theory behind it, or being able to derive it from first principles. That's very definition of not knowing maths and still being able to write software.
So what are these apps so I can avoid them? Because if you don't understand basic SQL, I don't want to use your apps.
