The first two vectors listed differ only by one hexadecimal digit (the third group of characters) in the third position. The difference between the corresponding decimal values is 1, so the third vector should have a value that is 1 larger than the second vector in that position. However, in Anthony's calculation, the value in that position is the same for both vectors. Thus, error (B) has been made.
The fourth vector listed has a negative value in the third position. However, in Anthony's calculation, this value is positive. Thus, error (A) has been made. 
The fifth vector listed differs from the fourth vector only by one hexadecimal digit (the third group of characters) in the second position. The difference between the corresponding decimal values is 1, so the fifth vector should have a value that is 1 larger than the fourth vector in that position. However, in Anthony's calculation, the value in that position is the same for both vectors. Thus, error (C) has been made.
