Peyton says that the sum between two numbers can never equal zero. But this is incorrect, because it does not take into account the existence of negative numbers, that is, the possibility that one of the numbers involved in the addition operation is a number less than 0. Thus, every negative number at If the same number is added but in positive values, the number 0 will be the result of said mathematical operation.

For example, in the following mathematical operation this situation is verified: -5 + 5 = 0.
