Hexadecimal calculations are the same as decimal calculations, both adding and subtracting numbers in the same digit, except that hexadecimal is a full hexadecimal system. For example: DFH+02H, the calculation process is:

F+2, full hexadecimal carry 1, remainder 1, D+O=D, plus carry 1, becomes E, so the result is E1H. I didn't make a mistake. The "H" at the end of course represents hexadecimal and does not participate in the calculation.
