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.
-244 is an integer, rational and real number
Answer:
Mass determines how fast a car can accelerate. Since a car accelerates slower with more adults, and faster with less adults, this means that the mass has a big impact on acceleration. Therefore, we can conclude that the mass determines how fast a car can accelerate.
