So why did you do so long as if you understand what 'base' means here? Let's try to explain it 'my way'. You must distinguish between the designator and the designated. E.g. when I ask you what a chair is, you could say 'it is a piece of furniture, that is designed to sit on'. You would feel pretty fooled if I would answer 'no, it is a word of 5 letters'. (I should have written then 'chair', between single quotes, to make clear that I meant the designator, not the designated. But hey, I wanted to fool you.) On the other side the same designated can be designated in another language, e.g. in Dutch as 'stoel'. Science usually does not change when you change the language. It is the same with numeric bases: on one side there are the numbers, at the other side there are their representations. Mathematics, and therefore all sciences using mathematics, are of course independent of the number base you use to express the numbers. Here a list of 'objects' and some translations: Chair Stoel translation in Dutch 666 29A translation in hexadecimal 666 1232 translation in octal 666 1010011010 translation in binary 666/18 = 37 29A/12 = 25 translation in hexadecimal 666/18 = 37 1232/22 = 45 translation in octal 666/18 = 37 1010011010/10010 = 100101 translation in binary So in the second column, we have only translations. The maths stays exactly the same, just a the physical characteristics of a chair are exactly the same as een stoel. We just have to keep an eye on which language we use, and be consistent. As an example: if we would think that '1232/22 = 45' is written in decimal, it would be wrong: in decimal 1232/22 = 56. But those are just symbols. You should always be aware of what they mean. You meant tan( #$@ ) = @ (assuming the last symbol in your 'language' stands for '0' ). Numeric Bases was the gap I had.. "Thanks" for clarifying this. This reminds me of "cryptography" or The "Ceaser Cypher " That uses "keys" a position and an output "letter by letter" where the key is a constant.. I know this sounds weird of a question. But what base does algebrea use? I ask becuase it has a 2 above the x: x^2 I found this for Numeric Base.. In a positional numeral system, the radix or base is the number of unique digits, including the digit zero, used to represent numbers. For example, for the decimal/denary system (the most common system in use today) the radix (base number) is ten, because it uses the ten digits from 0 through 9.

In base 10 there are 10 single digits (if you include 0) and no single digit for 10. So to count to 5 in base 10 you can count 1, 2, 3, 4, 5.

This question was intended to help you think about your question on bases. In modern times we enjoy a very efficient representation of numbers the means the 'base' is the count (number or integer if you like) of different symbols that are required to represent any number value whatsoever, when used in combination. So base 2 has two symbols :- 0,1 and base 10 has 10 symbols:- 0,1,2,3,4,5,6,7,8,9 The next number in the base 10 system is represented by a combination of two existing symbols as 10. Using only two combined symbols will take us up to 99 and then we require to start combining 3 symbols for 100 As soon as we start combining symbols we also require a convention to distinguish between say 32 and 23. This modern convention is one of the strengths of the modern system. However it was not always so For instance Roman and earlier civilisations used fewer symbols and as a consequence they representations contained more than one base, which made their arithmetic much more difficult. When I think of 1000 and 1, I see many things.. I see a conversion factor = 1 as in the inverse of this times 2 = 1/2 1/10^3 =0.001 where 1/0.001 "un" does the conversion, I also see 1010 looks like a binary number "who knows." I also see units of kg, or even microns...Its very hard to say what I see.. When I see "our more popular choice of base 10 I see both base 10 and base 2 as x^2 x= base 10 ^2 = base 2 Why would I think this?? For the rule of "like terms." By the way....How does minutes, hours and seconds apply to any of this to be something "reasonable" as for as the human perception of time goes?? In other words we do well with 26 = 26 letters of the alphabet, but how do we link numbers to "time?" Edited December 14, 2020 by CuriosOne Link to post Share on other sites

I will be trying to explain it in simpler terms. Any quantitative thing is a number. We use 10 characters 1,2,3,4,5,6,7,8,9,0 to represent them. Count how many characters we use? It's ten characters. Therefore our standard base of calculation is ten. Now imagine a civilisation living in a far off galaxy (don't ask questions like where are they bla bla, I'm just trying to explain). They evolved just like us. However unlike us, they are familiar to calculate numbers in base 4. They use the characters @,#,$ and & to represent all kinds of numbers. So they have base 4. That's basis. It has nothing to do with calculus or trigonometry. Trigonometry doesn.t require a special base. Why would it? tan 45 =1 in our base and character set. It will be @ in that far off civilisation's base and character set. That doesn't mean the two things are different. If you find it hard to understand, for a moment forget everything about number system and things taught. Try to see what I'm trying to say. 0 9 8 7 6 5 4 3 2 1 is understood, but when we add these to "units" from derived math formulas is where I get confused, very confused and "one of the reasons are:" You cannot have 60 seconds in one "completed cycle" ie time doesn't say 1:60 pm, it goes from 1:59 pm to 2:00 pm in a cycle of 59 seconds, not 60...Is this correct?? So what happens when we apply your explanation to time? Do we have 0->59 charectors of time??

Always assume base ten until told otherwise or if it is obvious in context(dealing with base-16 hexadecimal codes with letters as numerals for example). This is only alongside numbers, but you would normally use subscript to identify the base being used(if it needs to be made obvious). The number indicating the base, should itself be in base ten to avoid confusion. ie. 5 in base ten = 5_{10} An old joke goes that there are 10 kinds of people in this world, those that understand binary and those that don't. The joke being that 'one-zero' in binary or 10_{2}, actually means just two in base ten. You already understand counting in different bases, you just have to adjust your thought process slightly to see that. If I say 90 minutes from 3 AM, your brain will automatically add the two correctly and give you the correct time, without you even noticing it.

Yes indeed all very true But there are other considerations as well as the bare base number, we take for granted and therefore tend to forget. Firstly there is the positional notation we use today. For programmers who often split or group digits together to form nybbles, bytes and words etc there is also this grouping convention At machine level there is also the question of what is used to represent the 1 an 0 symbols.

This only has meaning if we first state the base (in my case 10, in your case something else) and then it still requires us to agree the meaning of each place. Furthermore if we have two such numbers say 1111 and 1001 we have the question of the convention about the meaning of putting these two together. Do we just add them ? If so by what rules ?
