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 342, we get 342 - 0 = 342. Similarly, if we subtract zero from 902, we get 902 - 0 = 902.
