I downloaded Sage 8.9 for Windows and want to use it to do some matrix computations. I do not have any prior experience in programming. So far I've been able to use the SageMath 8.9 Console to declare variables, define matrices, and multiply them together. But I want to write a program which does these computations successively and have SAGE implement it, rather than me typing in the commands one at a time.
I haven't been able to find how to do this in any tutorials. I don't understand where exactly I should be writing the code, how to save the file, how to get SAGE to read the program I wrote and implement it.
