Addition is commutative for natural numbers.
Idea: “Commutative” means we can change the order of the numbers and the answer stays the same.
With symbols:
Take two natural numbers (a) and (b).
Add in one order: (a + b).
Swap the order: (b + a).
Both give the same total.
So, (a + b = b + a).
With numbers:
(2 + 5 = 7).
(5 + 2 = 7).
Same answer, (7).
Conclusion: The order does not change the sum, so addition is commutative for natural numbers.
