Nice to meet you.  
I am a beginner beginner.  
I’m going to start with a very simple addition program…  
I want to show the case of true and false in the pop-up window.  
How can I do it?

Dynamic[MatchQ[x + y, z]]was the answer!! I found it. Thank you.

But, what if you check true or false and want to reset it again?

`Column[{Row[{InputField[Dynamic\[x\], Number]; x = RandomInteger[50], "+", InputField[Dynamic[y], Number]; y = RandomInteger[50], "=", InputField[Dynamic[z], Number]}], PopupWindow[Button["Click Here"], {Dynamic[MatchQ[x + y, z]], Button["Reset", DialogReturn[***Refresh[]***]]}]}]`

I want to go back to the beginning when I press the button, but I don’t know.  
Still, it’s fun to know one by one.
