In questions like, when asked to find the edges or nodes in the DAG of following expression,

a=a+b*c-(a+b)+(b*c)

do we also consider "=" as a node and its related edges?

No,you should not conisder "=" while finding minimum nodes,but if in options you should not find any option without "=",then you may try using "=".

No we dont consider the equal sign , The answer for it will be , Number of Nodes = 8 , number of edges = 10.
