I did not know.

Answer 3

its in decimal only. so simply add as you would add two decimal numbers

Answer 4

BCD is like converting each digit into Binary
921 base 10 = 0000 1001 0010 0001
763 base 10 = 0000 0111 0110 0011
Add them together still the same answer..
1684 base 10 = 0001 0110 1000 0100
