I was literally today years old when I learned even this much about binary.
I was also today years old when it hit me that it goes by a "base 2" system (if my terminology is right, at least).
Meaning...
2 = 10
2^2 = 100
2^3 = 1000
2^4 = 10000
(And presumably 2^5 would have been 100000, if the gif had gone on any longer.)
