Flash Buttons Begginer trouble.

Im working on a flash game. Im using Adoe flash CS5 & action script to create it. Im okay as far as designing the layout but Im weak on using actionscript 3.0 to manipulate stuff. Ive created buttons but dont know how to use them i.e right or wrong answers effect. anyone who is good at actionscript can help. Im creating a game like this one below http://lexiquefle.free.fr/num.swf
Anyone mind teaching me how to make a button explode (when the player gets it right) like in the above game

Like in the above french counting game are the alien ships buttons? Id like someone to teach me how to make a right/wrong answer button and their actionscript instructions
