(i)

By Commutative property, i.e., a+b=b+a

Therefore,

(ii)

By Commutative property, i.e., a+b=b+a

Therefore,

(iii)

By Associative property, i.e., (a+b)+c=a+(b+c)

Therefore,

(iv)

By Associative property, i.e., (a+b)+c=a+(b+c)

Therefore,

(v)

By Associative property, i.e., (a+b)+c=a+(b+c)

Therefore,

(vi) 0,0

0 is the additive identity that is, if we add 0 to any number the result will be the number itself.

a+0=0+a

Also, By Commutative property, i.e., a+b=b+a

We get,
