If you denote the set of rationals with R, whats the notation for real numbers?
One is the reflection while the other is the inverse. I hope this will help to clear your thought. / Cheers
holy crap this actually made sense! I thought this was going to be much more difficult to understand... Only thing I dont understand is the "infinity" vertical line... what defines where that is?
thanks for the video
@moikboy: My mistake, mate, sorry... the set of rational numbers should be denoted with the blackboard bold Q. Let me know if you spot any other error. Thanks for pointing the mistake!
I have a question at time 1:12. How is this point P+Q. According to another video posted by you, the reflection of P*Q is P+Q.
felicidades
Towards the end of your video you say that not every integer is a rational number and that every rational number is an integer. Isn't it supposed to be the other way round?
