I feel like you missed the point I was trying to make.

Sure, a teacher framing the necessity of learning math as "you don't always have calculator" is pretty lazy answer that doesn't really get to the point. In my experience, teachers rarely even made this point, students did that tried to argue that Mathematics was pointless when you have calculators.

But my point was that actually knowing these concepts is good for complex reasoning you can do in all aspects of life. Whether you have the calculator with you or not.
