Adding and subtracting an SN what do we need?
To add and subtract an SN (Supplement Number), we would typically need:
1. The starting base number: This is the original number from which we will add or subtract the SN.
2. The SN value: This is the specific number we want to add or subtract from the base number.
For example, if the base number is 10 and the SN is 5, to add the SN to the base number, we would perform the operation: 10 + 5 = 15.
To subtract the SN from the base number, we would perform the operation: 10 - 5 = 5.
It's important to note that an SN can be a positive or negative number, and the operation should be adjusted accordingly for addition or subtraction.
