Symbols of octal and hexadecimal system?
Octal: 0 1 2 3 4 5 6 7 Hexadecimal: 0 1 2 3 4 5 6 7 8 9 A B C D E F
What is special about number nine?
Nothing. It just happens to be the largest digit and that is probably because we count in ten and that, in turn, is because humans have ten fingers (including thumbs). The divisibility rule for 9 etc would work with any base. The number 7 in octal, or F (=1510) in hexadecimal have the same properties.
Does 3EO and 3Eo means the same in hexadecimal notation?
Hexadecimal uses the digits 0-9 and the letters a-f (in either upper case A-F, or lower case a-f). You appear to have used a letter O in upper case and lower case (o). Neither is a valid [standard] hexadecimal digit; so 3EO and 3Eo both mean the same in hexadecimal: a non-valid number. 3E0 and 3e0 are both valid hexadecimal numbers that mean the same (as the decimal number 992). In C, to signify a hexadecimal number it is preceded by 0X or 0x (that is zero-letter X), as in 0x3E0, etc.
What number system uses the digits 0 9 and the symbols A F?
9
What number system uses the digit 0 to 9 and the symbols a-f?
It is called Hexadecimal
What is the hexadecimal number F equal to in binary?
1111
Write a program that prints a table of the binary, octal and hexadecimal equivalents of the decimal numbers in the range 1 through 256?

What is the number fifteen is equal to in hexadecimal?
15 base 10 equals F base 16
If binary is base 2 maths what is base 8 maths and base 16 maths called?
Base 8 is known as octal and base 16 is hexadecimal.. In octal, 0 to 7 are used, so if we counted to 20, the progression would be as follows: 1,2,3,4,5,6,7,10,11,12,13,14,15,16,17,20,21,22,23,24 In hexadecimal, the numbers 0-9 are used and the letters A-F are used. Counting to 20 would be as follows: 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,10,11,12,13,14
What does the digital signal 1111 mean in human code?
Depends on the encoding. It is probably 0xF (15), but it could be -1 (if 4 bits in 2's complement), or any other value if a non-standard encoding. the coding can be octal or hexadecimal the value in decimal does not change in octal it is 17 in hexadecimal it is F in decimal is 15. ALL of these numbers are right it depends of what code the reference is to
Why is it easier to convert numbers from binary to hexadecimal than decimal to hexadecimal?
A binary number system has two states '0' '1' for a long word in bits it can be as follows 101010101010101010101011 intimidating RIGHT? it can be represented in groups of 3 bits in octal 10/010/101/010/101/010/101/011= 22525253 digital or in group of 4 bits as 10/1010/1010/1010/1010/1010 = 2AAAAA 111 =7 octal 1111=f F in hexadecimal numbers 1000 =8 1010 =10 or A
