Simplifying the values in an association

Question

How can I simplify the expressions of the values in an association in a simple way?

For example,

as = <|c1 -> x, c2 -> y x + y x + x x + y y , c3 -> z|> ;

as// Simplify 

does not give the result

<|c1 -> x, c2 -> (x + y)^2, c3 -> z|>

in Ver 11.0.

Answer 1

Simplify threads over lists, but not over associations, so

as // Normal // Simplify

{c1 -> x, c2 -> (x + y)^2, c3 -> z}

works, but

as // Simplify

doesn't. Recommend using Map

Simplify /@ as

Association[c1 -> x, c2 -> (x + y)^2, c3 -> z]

as suggested in the comments to your question.

Answer 2

AssociationMap[Simplify][as]

<|c1 -> x, c2 -> (x + y)^2, c3 -> z|>
