    Hello. I'm curious about the significance of the number 10. Is 10 a significant number in mathematics? In metrics, currency, and percentages 10 is an increment that people often use.

    My questions:

    1. Is 10 indeed a significant number in mathematics? If so, how is it significant?

    2. Would the number 10 be significant in metrics, currency, and percentages, if humas had 12 fingers, instead of 10?

    3. Is 10 mathematically, or universally significant, or is it significant becaue humans have 10 fingers? Would 10 be as significant of a number to aliens with 6 fingers for example?

    You speculations are correct. The number 10 is only important, because we have chosen to build our number-system around the basis number 10. This is because we have 10 fingers and toes, yes. In the binary number-system, 10 isn’t important at all. This is just as correct as our normally used 10-based number system.

    1) No… In basic arithmetic, 10 is important. But only because we have chosen to build up our system around it. This include the way we count and the “normal” logarithm, which base is 10.

    2) No. 10 is though, a “nice” number. It isn’t a prime, for instance. And 10 can easily be divided by 2. Had we chosen 7 to be the basis for our number-system, many calculations would have been slightly harder.

    3) 10 is only significant because we have chosen it to be. There do exist other number-systems, where 10 isn’t significant. Take a look at hexadecimals, for instance, where the base number is 16: http://en.wikipedia.org/wiki/Hexadecimal

    The value of "0" (Zero, Nil) is elementary in mathematical calculations. It was a revolution to add "0" to the end of number and reach new digital level, as

    ...The Italian mathematician Fibonacci or Leonardo of Pisa was instrumental in bringing the system into European mathematics in 1202, stating:

    "The nine Indian figures are: 9 8 7 6 5 4 3 2 1. With these nine figures, and with the sign 0 ... any number may be written."
    (Wikipedia)

    Number 10, and 10 based system are the representation of the power of 0.
    If you accept 0 as non-existing entity, and 1 (or any other number) as representative of existence, you get a new number when you add the symbol of non-existence next to an existence (10), and you get (a) a new number (b) a new digit. If there was not any 0, we needed to find a completely new symbol for number 10, so for number 20 and for every other number which has 0 or 0s. Check this:

    0.0001
    0.001
    0.1
    1
    10
    100
    1000

    This is obviously a human symbolic invention, and has no significance in nature like prime numbers. Yet, it is the most useful among others.

    Mathematics is essentially independent of the method used to represent numbers. The "base" is irrelevant for almost all purposes. In principle you can do mathematics using Roman numerals. Base 10 just happens to be convenient.

    10 is very important. It is the natural number that follows 9. Without it there would be an anomalously large gap between 9 and 11.

    It is also important for counting your fingers, if you have the same number as most of the population.

    10 is a very special number in maths as it is the biggest number which you can count to on your fingers.

    You may not have noticed, but you are speaking to a ghost (or maybe just a deceased troll).

    I would just like to add something about ten. The sequence of symbols "10" is always the base in the base that it is written. For example, 10 binary is two, 10 hexadecimal is sixteen and so forth.

    There are 10 types of people. Those who understand this, and those who don't.

    who would of thought binary would be such fertile ground for comedy
    everything is mathematical.

    "We" do not build up our system around number 10. There were Phoenicians (I hope I write corect). So, their system have taken account of angles created by lines. See the image below...The circles show to you how many angles are.
