Beyond that, a programmer who really understands recursion will: . Just what does the listener already understand? The equation of a straight line ()y = mx + b Where, if you were to imagine a straight line (as shown above), m: The slope of the line (The angle at which the line is turned) b: The intercept (On the Y-Axis, how much higher or lower is the line) y: The dependent/ target variable (The value we want to predict) x: The independent/ predictor variable (The variable that we use to make the prediction) Easy peasy lemon squeezy! The method has called itself. Like, number of legos in a box after applying the next step in the algorithm (which I'd advice to call something less scary, such as a turn or a step). Recursion when used in a programming or computer science context simply means when a part of your program calls itself.
