Answer #1

2EF10124h in bits: 0010 1110 1111 0001 0000 0001 0010 0100

flipping all the bits: 1101 0001 0000 1110 1111 1110 1101 1011

add one to this     : 1101 0001 0000 1110 1111 1110 1101 1100

consider d word is 64 bits in the microprocessor, pad the rest with Fh i.e. here:

N16(bits) = 1111 1111 1111 1111 1111 1111 1111 1111 1101 0001 0000 1110 1111 1110 1101 1100

N16(hexadecimal) = FFFFFFFFD10EFEDCh
