From your original post, it seems you may not have an external SdCard yet so buy a micro SdCard online from a store. Go for a 32GB capacity card because Apps are getting bigger and you might also like to store or at least backup, photos and music, etc. While you're in the shop, buy a carrier so you can use the card in your PC or laptop. It looks like a full size SdCard but instead has a small slot at the bottom end to house a micro card.
Look carefully round the edges of the device to see if there's a tiny black slot. If it isn't there, you'll have to take the back off. It only fits in one way and pushing it harder the wrong way round won't make it go in any quicker.
Then go into Apps>Settings>Storage and click on Mount SdCard and you're ready to move the Apps..
