The first time I ever heard of computers was in 5th grade – “new math”(circa 1962, approx.) – they taught us to count in base 2:
1=1, 10=2, 11=3, 100=4, 101=5 (there are only 2 digits: a zero, and a one).
I googled my questions, and received the following responses:
“The binary number system was first invented back around 1679 by Gottfried Leibniz. The modern, or present day binary code was developed by Claude Shannon.”
So, that is how computers compute?
Most people count in base 10.
At least that is what the math teacher told me in 5th grade in 1962.
I’m glad I am not required to fully understand it in order to use it! (My computer, that is.)
