The why to
complex question suddenly became crystal clear. But I wasn’t finished with
question as yet. I decided to use one of
search engine Google, latest innovation to get a bit more info about
why behind 1+1=2. I therefore connected to Google Answers! Google Answers is a sort of forum where individuals ask questions and tag an amount of money on
former. A specialist then answers your question and pockets
money. The best part of it though is if a question had already been asked and answered, anybody could view both
question and answer free of charge.
I entered ‘1+1=2’ is
search form and lucky me… somebody else had already asked why 1+1=2 and a mathematician had indeed given an answer.
I was satisfied and thought that that question was now filed. After having joked about it, questioned my kid brother, emailed astronomers and googled it, I think I now finally have a rather good and simple answer to
why behind 1+1=2.
“In number base systems higher than ‘2’, 1+1=2 because it is defined as such. Based on
definitions of
number ‘2,’
number ‘4’ and
mathematical operation of addition,
answer is always
same.”
Such a simple question, which is at
base of so many complex equations, isn’t that simple after all, is it? There is actually an entire book, Principia Mathematica by Whitehead and Russell (not
one by Sir Isaac Newton) which devotes several hundred pages to deriving and explanation of just why 1+1=2.
