Shorthand notation

We can use the shorthand notation a += b for a = a + b. Similar shorthand notation includes -= and so on.

Other shorthand notation uses x++ for x = x + 1 and x-- for x = x - 1.

Guess the results before looking at the consoleA window used for debugging, usually not visible on the page..
