How we can do exess -4 notation

Answer 1

To represent the number -4 in excess -4 notation, you need to add the excess value to it. Excess -4 means that the value -4 is used as a reference point, and any number above -4 is represented with a positive excess value, while any number below -4 is represented with a negative excess value.

To convert a number to excess -4 notation, follow these steps:
1. Determine the excess value, which is the reference point. In this case, it is -4.
2. Subtract the excess value from the number. For -4, subtract -4. The result is 0.
3. Represent the result with the excess value. In this case, 0 would be represented as the excess value (-4) with a sign indicating that it is below the reference point. Thus, -4 would be represented in excess -4 notation as -4-4.

Note: Excess -4 notation is not commonly used, as it is more common to use excess 127 or some other positive value as a reference point.
