F - 15.
10 - 16.
14 - 20.
Then
AH X 2H is 14H (H - hex).
10 - 16.
14 - 20.
Then
AH X 2H is 14H (H - hex).

A=10, B=2 then A*B=20 it is in hexadecimal then we want to change in hexadecimal so that if you divide with 16 then quotient=1 and rem=4. First we consider quo after rem. Therefore 14 it is in hexadecimal because you divide with 16.

A16 Here base is 16 which represents hexadecimal. 'A' in hexadecimal represents digit 10. Similarly 2 represents digit 2 in hexadecimal.
A * 2 = 10 * 2 = 20.
Digit 20 in hexadecimal representation is 14 (Conversion of digit 20 to hexadecimal: divide 20 by 16. we get;
1 as quotient and 4 as a reminder).
A * 2 = 10 * 2 = 20.
Digit 20 in hexadecimal representation is 14 (Conversion of digit 20 to hexadecimal: divide 20 by 16. we get;
1 as quotient and 4 as a reminder).

A a base16 X 2 a base16=(A*2) a base 16= 2*16^0+10*16^1=164 in decimal.
Start by dividing the number by 16, that is;
164/16 =10.25.
Division result is 10 is the decimal point,
The rest =0.25,
0.25*16=4.
So 10 +4=14 hexadecimal.

In hexadecimal A=10 and 2=2 then A*2=20.
20 is greater than 16, so we subtract by 6 from 20.
20-6 = 14.
20 is greater than 16, so we subtract by 6 from 20.
20-6 = 14.
