Hello there

I would like to hear the opinions of the members of this forum on the mnemonics methods employed on the memorization of math identities and formulae, more specifically the following identity:

x³ + y³ + z³ - 3xyz = (x + y + z)(x² + y² + z² - xy - yz - zx)

I´ve seen many people saying that you should try to understand what the expression is saying before just memorizing it, and I agree with them but sometimes the relations are way too abstract and not intuitive at all like the identity above.

Maybe there IS a method to make it all intuitive and properly remember it without having to rely on pure rote learning, if so, please leave a comment on it.
