This worksheet may help you to know about the commutative property of Addition. For all real numbers the added value will not differ depends on their order of addends. Let as assume a, b as a real numbers. This property states that
A + B = B + A
Proof for commutative property
Let A = 5, B = 7
L.H.S = (A + B)
= (5 + 7)
= 12
R.H.S = (B + A)
= (7 + 5)
= 12
L.H.S = R.H.S
The above example proves the theorem of commutative property of Addition
