Add the following BCD numbers, and convert theobtained BCD result into the
corresponding decimal, and then convert the decimal result into thecorresponding
binary, then compare the number of bits required for binary withthat required for BCD.
(1) 0111 + 0101
(2) 1001 + 0111
(3) 01010001 + 01011000
(4) 010101100001 + 011100001000
