2.3.4 Two’s Complement Arithmetic

What is the primary purpose of the 2's complement process in digital electronics?

• To design a subtract-er circuit

• To convert a positive number into its negative equivalent

• To multiply binary numbers

• To divide binary numbers

In a signed binary number system, what does the most significant bit (MSB) represent?

• The magnitude of the number

• The sign of the number

• The base of the number

• The parity of the number

How do you create a negative number in an 8-bit binary system using 2's complement?

• Add 2 to the binary number

• Add 1 to the binary number

• Invert all bits and add 1

• Invert all bits and subtract 1

What is the 2's complement of the binary number 00000101?

• 11111011

• 11111101

• 11111010

• 11111110

Which of the following is NOT a step in the 2's complement process?

• Subtract 1 from the original number

• Invert all bits

• Use the result for arithmetic operations

• Add 1 to the inverted bits

In a 3-digit decimal number system, how are negative numbers represented using compliments?

• Using a minus sign

• Using numbers 500 to 999

• Using numbers 001 to 499

• Using numbers 000 to 499

What happens if you disregard the overflow in binary addition?

• The result remains unchanged

• The result is incorrect

• The result is always positive

• The result is always negative

How do you check the result of a 2's complement operation?

• By inverting all bits of the result

• By performing 2's complement on the result

• By subtracting 1 from the result

• By adding 1 to the result
