A power of 2. In the decimal system, we use powers of 10, in the binary system, powers of 2. Other number system use some other number as their base; for example, hexadecimal (base-16) uses powers of 16.

Both make use of a zero symbol but Mayan numbers have 20 as a base whereas Hindu-Arabic numbers have 10 as a base.

1. Well, the number 10 is the base of the base 10 number system. The number 12 is the base of the base 12 number system. 2. I don't think the above expresses the answer quite accurately. The base ten numbering system (which is what we use in everyday life, because we have ten fingers, and which is called the decimal system) is restricted to ten integers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The integers of a base "twelve" numbering system could be represented by these ten integers plus two more, which we could call A and B (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B) So in a base "twelve" system the number we write as "12" in the decimal system would be written as "10", "23" would be written as "1B". The easiest way to understand this is to write the base ten numbers in a row and the equivalent base twelve numbers in a row immediately below. Base sixteen numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F) (hexadecimal) are commonly used in computing applications. - 3. Base of number system define how many digits it uses in that number system. As illustrated below Binary numbers as the name suggest uses only two digits which are 0 and 1. combination of 0's and 1's are used for representing other numbers. this system is used to communicate with machine so machine understandable language is known as machine language. Similarly in Octal number system 8(octal) digits starting from 0 thru 7 like wise decimal(=10) system 0 thru 9 hexadecimal(=16) 0 thru 9 and A thru F to constitute 16 digits. -

On computers.

The question does not seem to make any sense. Base 2 (or binary) can only use the digits 0 and 1. So 242 cannot be a number in base 2. That being the case, "242 base 2" is incomprehensible.

The decimal number system uses 10 different symbols to represent a number. The 10 different symbols are 0 to 9. It is a base 10 system unlike binary which is base 2 ( 0 and 1).

number systems use different bases. If a number only uses 5 symbols, then it is in base 5 The number system we use is base 10, because we have 10 symbols: 0123456789 so the number 1289 = 9x10^0 + 8x10^1+2x10^2+1x10^3 If it were in another base n, then converted to base ten abcd = dxn^0 + cxn^1+bxn^2+axn^3 A number system some may be familiar with is binary, which has a number base 2 since it only has 2 symbols, 1 and 0 In other number systems, the symbols can be different, such as in Babylonion, or other languages.

All number systems use a figure for some kind to stand for a number. The numerals 0,1,2,3,4,5,6,7,8,9 are the symbols for base 10, but base 2 uses only 0 and 1. Base 16 uses 0,1,2,3,4,5,6,7,8,9, A(for 10), B(for 11), C(for 12), D(for 13), E(for 14), and F(for 15) that makes 16 symbols to be considered as single digits for 16 numbers (0 thru 15). Each base must have that number of symbols for their individual numbers from 0 to one less than the base. Base 60 will need 60 such symbols, I've never seen them.

The Incas number system is base 2. the only digits you can use are 0,1

The symbols used are the numbers 0 to 4. Five is represented by 10, Twenty-five is represented by 100 and Sixty is represented by 220. For more info on the Quinary system (base 5) check the wiki reference below.

It is the number system that we use today, 0,1,2,3,4,5,6,7,8,9 , if that helps.

A power of 2. In the decimal system, we use powers of 10, in the binary system, powers of 2. Other number system use some other number as their base; for example, hexadecimal (base-16) uses powers of 16.
