C+CD = C(1+D)
= C.1 (1+A=1 and here we have 1+D which is also equal to 1 According to rule)
= C.
Hence proved.

C+CD = C(1+D) --> Where (1+D) = 1.
= C(1) = C.
= C(1) = C.

Because its not distributive law i.e. C (C+D).
Its C+CD = C (1+D).
=> C*1, C*D = CD.
Its C+CD = C (1+D).
=> C*1, C*D = CD.

But C+CD = (C+C) (C+D) = C (C+D).
Then how answer equals to C? Can someone explain why not this?
