Het getal 0 is het neutraal element van de optelling van reële getallen. Dit wil zeggen |
A. ∀ a ∈ : a + 0 = a |
---|---|
B. ∃ a ∈ : a + 0 = a | |
C. ∀ a ∈ : a + 0 = 0 + a | |
D. ∀ a ∈ : a + 0 = 0 + a = a | |
E. ∀ a ∈ : 0 + a = a + 0 = 0 |

Zero is the identity/neutral element under addition for the real numbers. This means that |
A. ∀ a ∈ : a + 0 = a |
---|---|
B. ∃ a ∈ : a + 0 = a | |
C. ∀ a ∈ : a + 0 = 0 + a | |
D. ∀ a ∈ : a + 0 = 0 + a = a | |
E. ∀ a ∈ : 0 + a = a + 0 = 0 |
