Which statement illustrates the inverse property for addition?
A)20 + (14 + 7)= 20 + (7 + 14)
B)14 + 0 = 14
C)7 + 15 is a real number.
D)20 + (-20)= 0

Question

Quizplus · Accepted Answer

The inverse property for addition states that every real number has an additive inverse such that when a number is added to its additive inverse, the sum is equal to zero. In option D, 20 and -20 are additive inverses, and their sum is equal to 0, thus illustrating the inverse property for addition. The inverse property for addition states that for any real number a, there exists an additive inverse −a such that a + (−a) = (−a) + a = 0. Therefore, the statement 20 + (-20) = 0 illustrates the inverse property for addition.
