What are hexadecimal numbers?
hexadecimal numbers are the a positional numeral system with a radix, or base, of 16.16 distinct symbols are used in the hexadecimal numbers.
How many symbols exist in the base of a number?
The number of symbols in the base of a number is equal to the base. Thus if the base is 2, there are two symbols, if the base is 8, there are eight symbols, if the base is 10, then there are ten symbols, if the base is 16, then there are sixteen symbols. Note that in each case "0" is a symbol. Also the base itself is not in the set of symbols. Thus there is no symbol for "2" in the base 2 system, no symbol for "8" in the base 8 system and so on. In each case the base is represented by the combination of the primitive symbols that run from 0 through (base - 1). Thus two in the base 2 system is represented as 10, eight in the base 8 system is represented by 10, and so on.
How many different symbols are used in the hexadecimal base 16 number system?
There are 16 symbols. The number of symbols is always the same as the base.
Can Three distinct planes can intersect at a line?
Yes, it is possible for three distinct planes to intersect at a line.
Why do add the alphabet to numbers in math?
The decimal system has only ten distinct symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Mathematics can involve calculation in other bases - one that is not so rare is the hexadecimal system - which is base 16. You need 16 distinct symbols for the hexadecimal system and so you use A, B, C, D, E and F along with the decimal digits.
