The reason for that is the extensive use of ‘jargon’ in Algebra classes. Rather than explaining what was really being done, teachers would use terms like “Transpose” and give a list of Rules of how to transpose, instead of simply stating that it amounted to performing the same operation to both sides of the equation.
My step-daughter got hung up on that crap until I spent a long evening discussing her difficulties, and realized that they had managed to turn simple operations into mystical magic.
I agree with that. I also found the same thing in business -- execs just talking lingo out of their azzes.
