Create a simple calculator program that performs four operations $(+,-,*,/).$ You must comply to

these makeup conditions:

$1.$ The background color is fading in and out slowly.

$2.$ Your name is moving around $$dancing$$ inside the stage. $[$Hint: Use timeline animation$]$

Make a calculator with one text field, working exactly like the calculator in your phone. Since the

input only can be coming from buttons, that should minimize the error checking code.
