thanks for the help, I'll check it out.
The multiplicative identity is defined such that if we let e be the multiplicative identity:Jonny_trigonometry said:yes, I understand that I'm not talking about ordinary multiplication on the reals as the rest of the world knows it.
hmmm... ok, I'm startin to get it... but! what if -1 is the multiplicative identity?
how far back do the rules go? does it stop at the multiplicative identity? or is there a reason that the MI must be positive 1?
