Posting the line of code Dave uses in the video for reference:
document.write('<p> Sorry. The number was ' + randomNumber + '</p>');
Now for the explanation.
If you removed the + sign before the closing paragraph tag, the code would crash since you would be telling the browser to write out "Sorry. The number was ", then it would hit the plus sign telling it to append the value of randomNumber to the end of the line, then it wouldn't know what you wanted to do with the closing paragraph in quotations since there isn't an operator telling it to concatenate it to the end of the line.
The plus sign simply tells the browser to add it to the end of the line.
A shorter explanation would be that the browser would understand everything up until it added the value of randomNumber to the end of the line, then it would expect a semi-colon to end the declaration. Instead, it gets more code and doesn't know how to process it.
Good luck with the course!

Since your string starts with a <p> tag it needs the closing </p> tag and unless you include the + and wrap the closing </p> tag in quotes like this + "</p>"); or this + '</p>'); your html will be missing the closing tag it needs.
