carry/overflow problems. I did some of them, I am not sure if they are though :'-(

The same integer arithmetic hardware (or called algorithm) works exactly 1 point the same, without any special considerations, between unsigned subtraction and signed subtraction. * True False The same integer arithmetic hardware (or called algorithm) works exactly 1 point the same, without any special considerations, between unsigned division and signed division. * True False 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob0100 - Ob0110 * Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 Carry = 0, Overflow = 1 Carry = 0, Overflow = 0 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob1011 - Ob0100 * Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 Carry = 0, Overflow = 1 Carry = 0, Overflow = 0 1 point The same integer arithmetic hardware (or called algorithm) works exactly the same, without any special considerations, between unsigned addition and signed addition. * True False 1 point The same integer arithmetic hardware (or called algorithm) works exactly the same, without any special considerations, between unsigned multiplication and signed multiplication, if the product has the same number of bits as the source operands. * True O False 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob0100 + Ob0110 * Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 O O Carry = 0, Overflow = 1 O Carry = 0, Overflow = 0 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob 1100 - Ob0110 * Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 Carry = 0, Overflow = 1 O Carry = 0, Overflow = 0 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob 1100 + Ob1110 * Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 Carry = 0, Overflow = 1 Carry = 0, Overflow = 0 1 point In a 4-bit system, what is the carry and overflow flag for the following calculation: Ob0100 + Ob0010* Carry = 1, Overflow = 1 Carry = 1, Overflow = 0 Carry = 0, Overflow = 1 Carry = 0, Overflow = 0
