1. What is the difference between hexadecimal and decimal numbers?
   Decimal numbers are 0 thru 9 while hexadecimal adds 6 more digits via letters A thru F.
   So the decimal system has 10 digits while the hexadecimal has 16 digits.

2. Which are the extra “digits” we get in hexadecimal?
   A,B,C,D,E,F

3. What is the difference between using lower case or upper case letters?
   There is no difference.

1. What is the difference between hexadecimal and decimal numbers?

The difference between hex and dec is that Hexadecimal is a base 16 number system and Decimal is a base 10 number system. Hexadecimal uses 6 extra digits to represent its numbers.

2. Which are the extra “digits” we get in hexadecimal?

The extra digits are: A, B, C, D, E, and F

3. What is the difference between using lower case or upper case letters?

As far as the hex number system is concerned there is no standardized difference.

4. Hex for 34 is 22.

1-What is the difference between hexadecimal and decimal numbers?
A* The difference between a hex and a decimal is
that a hex also contains letters. Hex numbers are formed by a correlative Mix from 0-9 and then A - F from 10 - 15

2-Which are the extra “digits” we get in hexadecimal?
The hex system, or hexadecimal, is a number system of base 16.
Because the decimal system only has 10 digits, the extra 6 digits
are represented by the first 6 letters in the alphabet.
For example, a hex value of B would be represented as 11 in decimal form, or binary value of 1011

3-What is the difference between using lower case or upper case letters?
A* there is no difference

4- What is hexadecimal for 34? (Use your head!)
A* 34 in hex is 22

1. Decimal is base 10, having ten numerals, 1 through 10. Hexadecimal is base 16, having sixteen numerals, 0 through 9, and then continuing A, B, C, D, E, and F. Decimal is best for humans because we have ten fingers so it is our default natural counting system. Hexadecimal has various uses in computing that make it a better counting system for those purposes.

2. A, B, C, D, E, F

3. There is no difference whether we use upper-case or lower-case letters in hexadecimal. They both work.

4. Base ten 34 = Hexadecimal 22

[Kieran]

1. Hexadecimal numbers are in base 16 - Decimal numbers are in base 10.
2. The extra digits in the set are, in decimal, 10 - 16, which are represented by the letters - A, B, C, D, E & F
3. There is no difference between using upper case, lower case, or even a mix of the two.
4. Hexadecimal for 34 is; Ox22

[FuriousD]

1. Decimal is base 10 and uses digits 0-9. Hexadecimal is based 16 and uses digits 0-F

2. The extra digits are A,B,C,D,E & F which represent 10,11,12,13,14 & 15.

3. Upper case and lower case are treated the same. 0xd = 13 decimal, 0xD = 13 decimal.

4. 34 decimal = 0x22.

2. Which are the extra “digits” we get in hexadecimal?
A,B,C,D,E,F

3. What is the difference between using lower case or upper case letters?
there is no difference.

1. What is the difference between hexadecimal and decimal numbers?
   Hex: Uses 0 through 9 in combination with a through A,B,C,D,E,and F. This allows more combinations. base of 16
   decimal: uses just 0 through 9 limiting the amount of combinations that can be made.
   base of 10

2. Which are the extra “digits” we get in hexadecimal?
   A, B, C, D, E, F

3. What is the difference between using lower case or upper case letters?
   There isn’t much of a standard in terms of upper versus lower case. A3F is the same number as a3f is the same number as A3f .

4. What is hexadecimal for 34?
   0X22 is the hexadecimal number for 34. (I had to write this one out haha)
   0x is used to identify that it is a hexadecimal number

This was another good website to reference. https://www.wikihow.com/Understand-Hexadecimal

[KryptoDr]

1. Decimal uses only 10 unique digits (0-9) whereas hexadecimal consists of 16 unique digits (0-9 and A-F)

2. A-F, which represtens 10,11,12,13,14,15

3. There is no difference. It doesn´t matter if you are using upper or lower cases.

4. 0x22

1. What is the difference between hexadecimal and decimal numbers?

Hexadecimal – also known as hex or base 16 – is a system we can use to write and share numerical values. In that way it’s no different than the most famous of numeral systems (the one we use every day): decimal. Decimal is a base 10 number system (perfect for beings with 10 fingers), and it uses a collection of 10 unique digits, which can be combined to positionally represent numbers.

1. Which are the extra “digits” we get in hexadecimal?

A, B, C, D, E, and F

1. What is the difference between using lower case or upper case letters?

None

1. What is the difference between hexadecimal and decimal numbers?
   The difference is that hexadecimal can represent a much larger sample size (of, for example, base 10 or decimal numbers). Decimal is a 10 digit system whereas hexadecimal allows a 16 digit (or character) counting system.

2. Which are the extra “digits” we get in hexadecimal?
   ABCDEF

3. What is the difference between using lower case or upper case letters?
   There is no difference. Also, as an aside, the letters a, b, c, d, e and f whether in upper or lower case, cannot be confused with numbers (as can the letters capital i [ I ], lower case L [ l ], upper or lower case o [ o or 0 ] - which could all be confused with the numbers 0 or 1).

There exists base64 which does include these characters that’s why for bitcoin addresses base58 is used which omits them, making misinterpretations of the address less likely

[cryptocrom]

I had come across that when I first got into my Bitcoin research, I don’t know how many times these characters have caught me out in other applications etc. Satoshi has thought of everything!! haha
