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

Translation in   E N G L I S H

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