Two's Complement Arithmetic Concepts

The video tutorial explains arithmetic operations using two's complement. It covers the process of converting numbers to two's complement form, adding binary numbers, and checking the MSB to determine the result's sign. Two examples are provided: solving 25 - 14 and 14 - 25 using two's complement arithmetic.

What is the first step in performing arithmetic operations using two's complement?

• Add the numbers directly

• Convert numbers to two's complement form

• Check the MSB

• Ignore any carry

What should be done if there is a carry after adding two binary numbers in two's complement?

• Subtract the carry

• Multiply the carry by 2

• Add the carry to the result

• Ignore the carry

In the example of 25 minus 14, what is the binary representation of 25 in 8-bit form?

• 00010101

• 00011100

• 00010011

• 00011001

What is the result of 25 minus 14 using two's complement arithmetic?

• 11

• 15

• 9

• 13

In the example of 14 minus 25, what is the two's complement representation of -25?

• 11011000

• 11100111

• 11011001

• 11100111

What is the result of 14 minus 25 using two's complement arithmetic?

• -15

• -13

• -11

• -9

What does a MSB of 0 indicate in the result of a two's complement operation?

• The result is negative

• The result is in decimal form

• The result is positive

• The result is zero

What does a MSB of 1 indicate in the result of a two's complement operation?

• The result is in decimal form

• The result is positive

• The result is zero

• The result is negative

How do you find the two's complement of a binary number?

• Find the one's complement and add 1

• Subtract 1 from the binary number

• Find the one's complement and subtract 1

• Add 1 to the binary number

What is the decimal result of the binary number 1011 in two's complement?

• 9

• 11

• 12

• 10
