Terminal does not recognize -add channels command

I am new and am configuring the terminal for my Anaconda Notebook to start the Introduction to Python Programming course.
I have set up the new environment (python_programming) and have changed from base to the new environment. But when I enter the -add channels command, I get an error response from conda that it does not recognize the arguments. Screenshot attached.
Please help!
FYI, I am running Google Chrome on an Intel Mac.
Thank you.

Hi -
Can you try --add and let me know if that works.


Hi Priya,

Yes, that seemed to work. Screenshot attached.

Thank you.
