Properties

The subtraction operation has important properties

• Neutral element
  The neutral element in subtraction is zero, meaning that subtracting zero from any number results in the same number. This is because zero is the only number that, when subtracted from any number, does not change its value. For example, if we subtract zero from 687, we get 687 - 0 = 687. Similarly, if we subtract zero from 933, we get 933 - 0 = 933.
