Subtraction is not commutative for whole numbers like at least three different pair of numbers to verify it

Answer:
Step-by-step explanation:Given any natural number, you can add 1 to that number and get the next number i.e. you get its successor.
The successor of 16 is 16 + 1 = 17, that of 19 is 19 +1 = 20 and so on.
The number 16 comes before 17, we say that the predecessor of 17 is 17–1=16,
the predecessor of 20 is 20 – 1 = 19, and so on.
The number 3 has a predecessor and a successor. What about 2? The successor is 3 and the predecessor is 1. Does 1 have both a successor and a predecessor?
We can count the number of children in our school; we can also count the number of people in a city; we can count the number of people in India. The number of people in the whole world can also be counted. We may not be able to count the number of stars in the sky or the number of hair on our heads but if we are able, there would be a number for them also. We can then add one more to such a number and get a larger number. In that case we can even write the number of hair on two heads taken together.
