Show that m = m + 0 = 0 + m, for all m belonging to naturals, that is, 0 is a neutral element of the addition operation in
Question
Answer:
Certainly! To show that 0 is the neutral element of addition for natural numbers (N), we need to demonstrate that for any natural number 'm,' the following equations hold true:
1. m + 0 = m
2. 0 + m = m
Let's prove each of these equations:
1. m + 0 = m:
We can prove this by induction.
Base Case: For m = 1,
1 + 0 = 1, which is true.
Inductive Step: Assume it's true for some natural number k:
k + 0 = k
We need to show that it's true for k + 1:
(k + 1) + 0 = k + (1 + 0) (using associativity)
(k + 1) + 0 = k + 1
So, by induction, m + 0 = m for all natural numbers m.
2. 0 + m = m:
This can be proven similarly by induction.
Base Case: For m = 1,
0 + 1 = 1, which is true.
Inductive Step: Assume it's true for some natural number k:
0 + k = k
We need to show that it's true for k + 1:
0 + (k + 1) = (0 + k) + 1 (using associativity)
0 + (k + 1) = k + 1
So, by induction, 0 + m = m for all natural numbers m.
Therefore, we have shown that 0 is the neutral element of the addition operation for natural numbers, as both equations m + 0 = m and 0 + m = m hold true for all natural numbers m.
