It?s a ?consistency? proof. Students in algebra do not yet have sufficient background to justify these things deeply with formal analysis.

If I were to guess, you confuse the emotion[1] of math with its pedagogy[2].

I claim that the pedagogy is universal, while the emotion is up to the individual.

[1]emotion - what you like about math, which varies from student to student.

[2]pedagogy - how mathematical awareness builds in a student, any student.
