Remember practicing multiplication tables as a kid and your teacher repeatedly asking you what "5 x 9" was until you got it right?
In this situation, the flag variable was whether or not you got the problem correct.
If you answered the problem incorrectly, the teacher would continue the loop of asking you the question.
However, if you answered the problem correctly, the teacher end the loop and stop asking you the question.
In other words...
A flag variable is a boolean value that signals to a while loop whether or not to continue running.
