Spend 15 minutes looking at the Functions you see when you right-click a Block Diagram. If you don't know what one does (for example, the one called "Square"), you can turn on "Context Help" (short-cut key is ^H), then if you hover over a function, a Help box will pop up.
While you are at it, you can expand some of the other sets of functions other than "Programming" (such as "Mathematics") and spend another period of time learning. One nice thing about LabVIEW is it just takes a few mouse clicks to put some functions on a Block Diagram, wire up a Control on their Input and an Indicator on their Output, and try them out to see if they do what you need.
