What is?
Subtraction is a fundamental arithmetic operation that involves taking one number away from another. It is denoted by the minus (-) sign, and the result of a subtraction is called the difference. Subtraction is the inverse operation of addition, meaning that if we add the difference to the subtrahend (the number being subtracted from), we get the minuend (the original number).

• subtracting: 2100;
• operator: -;
• difference: -1451.

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 649, we get 649 - 0 = 649. Similarly, if we subtract zero from 2100, we get 2100 - 0 = 2100.
