Hexadecimal numbers can be manipulated in exactly the same was as decimal. The digits we can use are: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. Let us take two numbers, say, 7 and 6. In decimal, we can count from 7 upward by 6... 8, 9, 10, 11, 12, 13. In Hexadecimal, we can do the same... 8, 9, A, B, C, D. Let's take two more numbers, D and 4. We count upwards from D by 4... E, F, 10, 11. Notice that after F, there is no other digit we can use, to we carry 1 to the 16's column and carry on counting to reach the final figure of 11Hex. This is just the same as the decimal procedure of carrying to the tens column after we pass 9. Once you have got your head around the idea of extra digits, the rest of it is as easy as decimal.
Pretty much the same way that you add decimal numbers, except that you roll over to the next digit after 7 instead of 9. 1+1 = 2 2+2 = 4 3+3 = 6 4+4 = 10 5+5 = 12 6+6 = 14 7+7 = 16 10+10 = 20 11+11 = 22 Or you can convert to decimal, add, convert back if that's easier. 11o = 1*8^1 + 1*8^0 = 9d 9+9d = 18d 18d = 22o
If you mean using the programming language, it'll do it automagically, for example, if you have in C:
int a = 0x389;
int b = 0x7A8;
int c = a + b;
then c will contain 0xB31 (in hexadecimal) - to display the value you would use:
printf("a + b = %X + %X = %X = c\n", a, b, c);
You can also convert to hexadecimal (for display) directly, for example:
printf("0x%x + 0x%x = 0x%x\n", 127, 207, 127 + 207);
which will display the sum in hex:
0x7f + 0xcf = 0x14e
Hex is only a convenient way to display the numbers to humans.
If you mean manually, yourself, then exactly the same way that you add in any other base.
Start at the right hand end, add the digits together and when it becomes greater than the highest digit that can be stored in a single digit, subtract multiples of the base, write the remaining digit in the answer and the number of multiples of the base subtracted is added as a carry to the next digit sum to the left.
With hexadecimal, just remember that:
0x8 + 1 = 0x9
0x9 + 1 = 0xA
0xA + 1 = 0xB
0xB + 1 = 0xC
0xC + 1 = 0xD
0xD + 1 = 0xE
0xE + 1 = 0xF
0xF + 1 = 0x10
A trick to thinking in hexadecimal is to remember that 8 is 1/2 of 16 and think of the digits above 7 as (8 + [0-7]), that is:
0x8 = (8 + 0), 0x9 = (8 + 1), 0xA = (8 + 2), 0xB = (8 + 3)
0xC = (8 + 4), 0xD = (8 + 5), 0xE = (8 + 6), 0xF = (8 + 7)
and remembering that 0x8 + 0x8 = 0x10.
Example:
0x389 + 0x7A8 = 0xB31
0x9 + 0x8 (= 8 + 1 + 8 = 0x10 + 1) = 0x11 = 0x1 carry 1
0x8 + 0xA + carry 1 (= 8 + 8 + 2 + 1 = 0x10 + 3) = 0x13 = 0x3 carry 1
0x3 + 0x7 + carry 1 (= 8 + 3) = 0xB
If you can't think using the fifteen single digits, work in decimal remembering the conversions:
0xA = 10
0xB = 11
0xC = 12
0xD = 13
0xE = 14
0xF = 15
For example the second addition above becomes:
0x8 + 0xA + carry 1 = 8 + 10 + 1 = 19 (= 16 + 3 = 0x10 + 3) = 0x13 = 0x3 carry 1

How do you solve octa-hexadecimal?
That depends what you want to "solve" for - in other words, what the question is. For example, whether you want to:* Convert from hexadecimal to decimal* Convert from decimal to hexadecimal* Count in hexadecimal* Add hexadecimal numbers* etc.
How can i add Hexadecimal numbers 2E and 34 without converting them into decimal?
To add hexadecimal numbers 2E and 34 without converting them into decimal, you first need to align the numbers by place value. Start from the rightmost digit and add each pair of digits, carrying over if the sum is greater than 15 (F in hexadecimal). In this case, 2E + 34 equals 62 in hexadecimal. The final answer is 62.

1 To develop a program using the ADI instruction to add the two hexadecimal numbers 3AH and 48H and store the result in memory location 2100H?
Oh, what a happy little question! To add the two hexadecimal numbers 3AH and 48H using the ADI instruction, you can first load 3AH into the accumulator, then use the ADI 48H instruction to add 48H to the accumulator. Finally, you can store the result in memory location 2100H. Just remember to take your time, enjoy the process, and trust in your abilities to create something wonderful!
