[René Oudeweg]

[Enkele aantekeningen over p-adic numbers en zijn toepassingen in de 
getaltheorie alsmede de rare eigenschappen van getallen in base 10 zoals 
uitgelegd in de onderstaande YT-video d.d. 6-6-2023

"A 10-adic number is similar except that we omit the sign and allow an 
infinite string of digits going off to the left; for example ··· 
87654321. This differs from real numbers such as 3.1415926 ··· which 
have an infinite string going off to the right."
