 I've (improperly) implemented the magic method. It's supposed to multiply six times seven and get 42. However, that's not what happens. After (not) much investigation, I am baffled and realize I want to know what the values of `part1` and `part2` are on line 5.

In the left bar near your code, you can double click (or right click and chose to turn on the breakpoint.) A little circle will appear showing the breakpoint i set.

 ## How can debuggers be used?
 
 There are a number of reasons why you might want to use a debugger. Three of the most common are:
 
 1. Fixing broken code - The debugger allows you to see the values of variables as the code runs. This allows you to see where it stops behaving as expected. 
-2. Understanding unfamiliar code - Seeing the values as the code runs can help you understand it better
+2. Understanding unfamiliar code - Seeing the values of each variable as the code runs can help you understand it better
 3. Tracing the path of the code - When stopping at a breakpoint, the debugger shows what classes/methods were called in order to get there. You can even click on them to see what the variables in scope at those points are.
