The identity element in addition states that adding what number to any number results in that number?

1
0
-1
2

The correct answer is: 0

The identity element in addition is defined as the number that, when added to any other number, does not change the value of that number. In the case of addition, that number is zero. When you add zero to any number, the sum is always the original number. For example, if you take the number 5 and add 0 to it, you get 5 (5 + 0 = 5). This property holds true for all real numbers: adding zero leaves the number unchanged. Therefore, zero is the identity element in the operation of addition.
