Hello I'm just new to AE Expression.

I want to know how can I decrease the value from every keyfram to another value. In my case : I set keyframe of opacity to 100 and I want it slowly decrease to 0 about 2 second after the keyframe.

Please help
Thanks

Why wouldn't you just add a second keyframe with a value of zero? It's hard to give you a solution without knowing exactly what you're trying to do.

Here are some examples that use time and linear() to fade layers in/out based on their in/out points:

You could also look at keyframing values in a Slider Control effect and have a simple expression (created using the pickwhip) that subtracts the value from opacity:
opacity - effect("Slider Control")("Slider");
