run/view the practice and the strings

first, I open the solution workspace and run it - it doesnt work. why?? (i didnt change anything)...

second, i dont understand the strings... i learned Java before and i know that always " show even times.... like "string" (2 times) or "your number is: " + number + ", very good!" (4 times).

this is command from the solution:

message += "userNum1 + " + " + userNum2 + " = " + (userNum1+userNum2);

the " show 5 times. why?!? (the " after the sign +=) its not working, just notice...

thanks!

1) In the video's workspace all the lines in math.js are commented out instructions so there is nothing to run. In addition you will have to add the math.js script to index.html

2) The beginning quote before userNum1 shouldn't be there. I checked the video @3:50 and there isn't a quote in the solution.
