Limits intuition
A limit describes the value a function's output gets closer and closer to as its input approaches some value, even if the function is never actually defined there: as x gets closer to 2, (x^2-4)/(x-2) gets closer and closer to 4, even though the expression itself is undefined at x = 2 because of division by zero. Limits are the idea that makes calculus possible: they let you talk precisely about instantaneous rates of change and the area under a curve, both of which involve values you can approach but never quite reach by plugging in directly.
