Explain, Subtraction is not commutative for whole numbers. 
Prove (a  b) ≠ (b  a) and what is this property called ? 
Solve (247  100) and (100  247). Are both same and what this property is known as ? 
If p = 77 and q = 33, explain commutative property of subtraction of whole numbers, which says that (p  q) ≠ (q  p). 
As per commutative property of subtraction of whole numbers we know that subtraction is not commutative for whole numbers. Explain this with the help of two different pairs of whole numbers.
