The BCD addition of 910 and 710 generates code groups of 1001 0111 and a carry to the next higher position. The final step in the problem is to:

A) add 0110 to the lowest order code group and then prefix the carry with three zeros.
B) ignore the lowest order code group because 0000 is a valid code group and prefix the carry with three zeros.
C) add 0110 to both code groups to validate the carry from the lowest order code group.
D) disregard the carry and add 0110 to the lowest order code group.

Question 2

How many BCD adders would be required to add the numbers 97310 + 3910?

A) 3 B) 5 C) 6 D) 4
