Ipad apps not showing Icon

Hello everyone so here is the deal there are several apps that I have downloaded and it said they installed so after they installedI went back to click on them but there is no icon for the app at all....My question is how do I go in and remove the program/app because it said it had been installed so it the apps have to be on there somewhere, or some remnants of them and I was curious as to what I need to do to uninstall them.

Thanks in advance.
