Hexadecimal addition

Slt ,je veux te donner une méthode ,dans la base 16 on a 1,2...9,A,B...F

Pour l'addition :

ex: 13

+9

3+9=12 qui correspond à C en base 16 donc 1 C comme réponse un autre exemple :

19+69=? tu fais 9+9=18 oops 18>16 donc on fait 18-16=2 écoute bien on ecrit

2 et on report 1 donc on aura 82 comme reponse !

Hello or Good evening,

To add in hex you should know that you are working in base 16. The principle of addition remains the same as in decimal or binary. To make your calculations easier, if you know how to add in binary you can do this:

A hex digit is replaced by 4 binary digits, hence:

Hex Binary
0.....0000
1.....0001
2.....0010
3.....0011
4.....0100
5.....0101
6.....0110
7.....0111
8.....1000
9.....1001
a.....1010
b.....1011
c.....1100
d.....1101
e.....1110
f.....1111

For example, if you want to add

a9 + b1 you do
10101001 + 10110001

Afterwards you perform the inverse operation and you have your result in hex.

This is the fastest method in my opinion.

Good luck

I hope that answers your question

JSS.j'ai.bon.là?

f1+29
1af3+e058
abc+def
how to solve this I want a simple method

when the sum = 16. in this case we must put a 0 and carry 1 .

example: 9 + 7 = 10 H.

from this principle we can easily calculate any QWord.

Good luck.

thank you

In fact to explain to you I want to start with addition in base 2 e.g.

10+1=11 ,11+1=100 ! take it easy you do 1+1=2 as we are in base 2 you do 2-2=0 and you carry 1 hence 100 in base 16 (0,1,2,3,4,....9,A,B,C,D,E,F)

example A5+A=AF , 10->A
11->B
...

AF+6=C5, F equals 15 ,F+6=21 ,21>16 therefore 21-16=5 and you carry 1 hence C5
