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.
Considering the lowest five digit hexadecimal number is 10000 (65,536) and the highest is FFFFF (1,048,575), there are 983,040 different hexadecimal numbers that are five digits.

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.
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.
To add the hexadecimal numbers 2E and 34, first align them by their least significant digits: 2E + 34 Starting from the right, E (14 in decimal) + 4 equals 18, which is 12 in hexadecimal (write down 2 and carry over 1). Next, add 2 + 3 + 1 (the carry) to get 6. Therefore, the sum is 62 in hexadecimal.
AAAAAAAAAAAA is the Hexadecimal.
If the above is decimal then in hexadecimal it is 2964492C2. If it is binary then in hexadecimal it is 7DA. If it is octal then in hexadecimal it is 49241208.
234 in hexadecimal is EA.
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!
That depends what you want to "do" with the hexadecimals - add, multiply, compare, etc. The first thing you would need to do is learn how it is defined.
The hexadecimal for 14 is the letter E.
60 in hexadecimal would be 3C
D63A
It equates to 26 in hexadecimal.
