Numbers

Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

An example of positive campaigning:

Why was binary number system formed?

Electronic and optical data storage and processing equipment can easily identify dichotomic behaviour: a choice of two positions: for example, on or off, pit or no pit, magnetised or not magnetised. It is much easier for a machine to unambiguously decide whether a particular memory location is magnetised or not magnetised rather than work out which of 10 levels of voltage it is at. The second option is much more likely to lead to errors. For that reason the binary system is well suited for electronic and optical data storage and processing.

What are the substets of real numbers?

I believe it's accurate to say that there are an infinite number of subsets

of real numbers. Not only that, there could be an infinite number of subsets

that have an infinite number of members.

A few of them would be:

  • the odd numbers
  • the even numbers
  • the even numbers between 10 and 20
  • the even numbers between 10 and 22
  • the even numbers between 10 and 24
  • the even numbers between 10 and 26
  • the integers greater than 137
  • the numbers between 4.0 and 4.1 that have more than 2 decimal places
  • the prime numbers greater than 68,597
  • the integers containing at least one '6'
  • the powers of '2'.
