= for equals, ≡ for identity?
Do any of you out there use ≡ for “identity”? In your own work? With little kids?
I am considering introducing it to 9th grade algebra students.
They think symbols are cool.
I know they get confused when solving 4(1-2b) = 2(3-b) – 2 , maybe the special symbol would help?
What do you think?
