Numeracy

Who remembers the Weekly Photo Project on G+ This image was created for the word simplicity.  It also works for numeracy.

WPP 2015 - Week 08 - Simplicity / Minimalism

Binary

There is nothing simpler in the computer world than binary.  Either something is on (1) or off (0).  The image illustrated is 1 + 1 = 2.  To understand this numbering system you need to look at each column from the right and double the number. so column 1 (the rightmost) = 1, column 2 = 2, column 3 = 4 and column 4 = 8.  So if column 4 has a one then it equals 8 and if column 2 has a 1 then it equals 2.  To get the value of the binary sequence you simply add the numbers together.  So in the picture you have 0 + 0 + 2 + 0 = 2.  If it had been written as 1010 then it would be 8 + 0 + 2 + 0 = 10.  This as simple as it gets and is the way that all computers run their programmed instructions.  EVERYTHING is either 1 or 0, on or off.  It doesn't get any simpler than that :)
