Answer:
The result is -63
Explanation:
First, we discover the Binary value of 151 which is 10010111.
1 = most significant bit and it represents the sign as negative.
Two's compliment of 10010111, is calculated by adding 1 to one's compliment. We get 01101001 which is 105 in decimal.
Therefore the value of A (the first part) is -105.
Second, the binary value of 214 = 11010110.
1 = most significant bit and it represents the sign as negative.
Two's compliment of 11010110, is calculated by adding 1 to one's compliment. We get 00101010 which is 42 in decimal.
Therefore, the value of B (the second part) is -42.
Simplify further,
A - B = -105 - (-42)
= -105 + 42
= -63
Therefore, the result is -63,
