FOILING is definitely a math thing, but is Troiling? Some notational fluency composing functions and a little algebra bashing is required to solve this marginally challenging mathematics problem that could fairly be labeled as deceptive.(Steven Stadnicki and ratchet freak, Java developer, lucidly debunked "proofs" that seemed visually plausible April 2014)
Squaring a binomial is a frequently used process which is why First Outer Inner Last is memorized, BUT what about squaring a trinomial!. This is the part where one has to understand the distributive property without relying on mnemonic crutches like FOIL.
Software engineer Peter Coles dons his math teacher pedagogy hat stylishly when he claims “there’s no understanding with FOIL”
PHD mathematician, educator and author David Joyce never used the word distributive property to justify the letters/steps in the acronym FOIL. He simply repeated the mindless process like so many other teachers who are under time constraints to cover all the topics listed on syllabus.
