If you want masses of people to be unable to think for themselves, be dependent on you for answers, and be unable to tell when you lie to them it's a very good idea to prioritize having an answer over understanding the steps needed to arrive at it.

The death of critical thinking. There are days when my sons have a hard time in school just because they ask questions, want explanations and to be given background. It turns out the current generation of teachers may already not be able to supply any of those.

But that is exactly how we learn this stuff.

As kids, we know what 4 is before addition is even mentioned. And we can count those 2 marbles and those 2 marbles and then those 4 marbles before learning the "+" sign.

If you think about it, we must know what 2 and 4 mean before we can learn what + means.

You need to know that addition is a thing and have reasonable confidence that 2+2=4 before attempting 2+3
