Answer:
Multiplication is commutative.
Step-by-step explanation:
Let n,m be two natural numbers.
We have to show that 
We will prove this by induction
For n = 1, we have
, which is true.
Let the given statement be true for n-1 natural numbers, that is,

Now, we have to show that it is true for n natural numbers.

which is equal to




Hence, by principal of mathematical induction, the given statement is true for all natural numbers.
