| The notebook has asked you to try a few calculations even before the ''typeof(10)'' statement. To do this, click on the section of text starting ''[1] Type different types of integers ...'' and then either select Insert -> Insert Cell Below from the menu, or use the quicker keyboard shortcut "control-m b" (or "ctrl-m b"). That is, hold the control key, type "m", and then let go of control and type "b". This will insert an empty Julia-code cell, which you can type Julia commands into and execute with shift-enter.

| + | When you want to execute a bunch of commands, it can get tedious to keep opening new cells. The "alt-enter" shortcut executes the current cell then immediately starts a new cell below. I've used "alt-enter" to compute a few powers of 10 as the notebook suggests. | ||
