Constant Rule
Definition
The constant rule states that the derivative of a constant term (a number) is always zero. In other words, when you take the derivative of a constant, it disappears.
Analogy
Think of a conveyor belt carrying boxes. If all the boxes are identical and have no distinguishing features, you won't be able to tell them apart because they're all constant. Similarly, when taking the derivative of a constant term, it becomes indistinguishable and disappears.
