Hi, > there is a way to tell to mathematica to write all passages from the > expression that i give, to the solution i get? Trace and TracePrint are close to what you want. They don't delve into internal functions and functions that have the Attribute ReadProtected. Maybe there are other limitations that I don't know of. Both have various Options with which you can filter the output, and without them they are usually producing tons of output that's hard to read. It takes a while to learn how to make good use of them. Also, keep in mind that the Trace*-functions are useful for debugging rather than understanding how mathematica evaluates certain expressions... albert
