0xff = 16 x 15 + 15 = 255 The letters A-F are used to represent the decimal numbers 10-15 (respectively) which are required to be held in one hexadecimal digit.
Hexadecimal is a way of writing base sixteen using the letters A-F to represent the numbers 10-15. In base 16, 43 is 2 sixteens and 11 ones, so it is 2B in hexadecimal, as B represents 11.
"The hexadecimal code of ABCDEF" is rather difficult to make. If you want the DECIMAL code for the HEXADECIMAL numbers A, B, C, D, E and F, then you get this explanation: Hexadecimal means 16 and if you are counting hexadecimal and you will start to count from 0 to 9 normally. Then you get A for 10, B for 11, C for 12 D for 13 E for 14 and F for 15.
1111111111111111 to base 2 (binary) is equivalent to FFFF to the base 16 (hexadecimal) which in decimal equals (15 x 16*3) + (15 x 16*2) + (15 x 16*1) + (15 x 16*0) = (15 x 4096) + (15 x 256) + (15 x 16) + (15 x 1) = 61440 + 3840 + 240 + 15 = 65535 Another way to look at this is that FFFF in hexadecimal is actually 10000 in hexadecimal minus 1 and we know 10000 in hexadecimal is 65536 and so FFFF in hexadecimal is 65536-1 = 65535
Hexadecimal is a number system whoose base has 16 numbers. Hexadecimal is usually represented as 0 through 9 and A through F. An example of counting from 9 to 33 follows. 9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21
The number 249 in hexadecimal would be F9. The digits in base 16 correspond to powers of 16 rather than 10. For a two-digit number, the place values are 16 and 1, and the usable values are from 0 to 15, with values 10 through 15 represented by letters A (10) through F (15). F9 = (15x16) + (9x1) = 240 + 9
Computer engineers use to use the hexadecimal code to program computers, or the base 16. Hexadecimal numbers use the digits 0 through 9, plus the letters A through F to represent the digits 10 through 15.
0xff = 16 x 15 + 15 = 255 The letters A-F are used to represent the decimal numbers 10-15 (respectively) which are required to be held in one hexadecimal digit.
15 base 10 equals F base 16
These are the hexadecimal digits and their decimal equivalents: 0 = 0 1 = 1 ... 9 = 9 A = 10 B = 11 ... F = 15
15 in the hexadecimal number system is represented by 21 in the decimal system.
Hexadecimal is a way of writing base sixteen using the letters A-F to represent the numbers 10-15. In base 16, 43 is 2 sixteens and 11 ones, so it is 2B in hexadecimal, as B represents 11.
It is -F.

It's 15 if it's in the units position. If it's in the 2nd position to the left of the hexadecimal point, it represents 15 times 16. At the 3rd position, it's 15 times 16 squared. At the 4th position, it's 15 times 16 cubed, and so on.
Expressed as a sum in hexadecimal form, F + D = 1C.
111111 in binary is 255 in decimal which is FF in hexadecimal (i.e. 15 units and 15 16s)
