"as most things multiplied by themselves = 1"

Is this from Commie Core?

no basic math i didn’t remember it fully so i looked it up. it is the Inverse property of multiplication or multiplicative identity not multiplied by itself but multiplied by it’s inverse. It’s been about 35 years since i did this stuff.
