perform operation

convert back into binary

let's understand by example (1CE)+(A2)

1CE=0001 1100 1110

0A2=0000 1010 0010

      = 0010 0111 0000 =270 (in hex)

You can convert using 8421.
0 to 9 are simply understandable then A=10 (1010),B=11 (1011),C=12 (1100), D=13 (1101),E=14 (1110) ,F=15 (1111)
