Chain rule

The Chain Rule is like a game of jumping and connecting stepping stones. To get to the end destination, you need to take several steps. For each step, you can use the Chain Rule to figure out how big the jump should be and where it will lead next.

The Chain Rule helps us figure out the rate at which something is changing, like the speed of a car or the level of water in a river. You can think of this like a math puzzle where each step in the chain gives us a clue on how to find the answer.

To use the Chain Rule, first you have to figure out what's changing. Then you have to figure out the rate at which it's changing (the speed or the level going up or down). For example, if you want to know the speed of a car as it's moving, you'll need to figure out how much the position of the car is changing (how far it's gone) divided by how much time has gone by (how long it has been moving).

The Chain Rule uses this rate of change to determine the size of each jump in the chain. For example, if the rate of change is 6, then each jump must be 6 times bigger than the one before it. This lets us keep track of the changes and figure out what the final answer is.
