Abstract Algebra - What is a Group? What are Groups?

Jesus Christ is NOT white. Jesus Christ CANNOT be white, it is a matter of biblical evidence. Jesus said don't image worship. Beyond this, images of white Jesus are not just blasphemous and criminal, white Jesus is from Satan ( the imposter.) Why? Let's look at what Satan does:
1) He is incredibly narcissistic and promotes himself shamelessly.
2) He misleads and confuses.
3) He pushes people away from Jesus Christ God, the Holy Trinity, the one and only messiah. White Jesus does all three of the above and more -- matching the ways of Satan.

Statues of Christ are equally offensive to God the Christ. While money is the biggest idol, Jesus spoke sufficiently against carved images.

This is the first of many videos on Groups and on Abstract Algebra. Enjoy!

Skip to first minute if you dont want to hear inspirational talk. Also, I should point out that the Integers do not form a Group for example under multiplication because 5, an integer, doesn't have a multiplicative inverse that is an integer. The multiplicative inverse of 5 is 1/5 but 1/5 is not an integer.

Hi! I have a question (it's not from the video). What is the meaning of that "+" filled by a circle ? I'm studying multivariable limits and there are some things that implies the R^n spaces and my knowledge of abstract algebra doesn't help me a lot. So, I have some problems to understand the theory. Thank you a lot!
