How do I use aggregation to find the average of a row?

Goryeo

A pleasant day/evening to the community. I hope you can help me again with my problem.

I have a dataset that has around 500 rows relating to student grades. It is really hard to explain in words but here's what the dataset looks like

student_id | Math | English | Science | PE | History | Computer 
student1           80         92             87         95        90           86
student2           87         95             91         98        94           90 
student3           84         90             88         94        84           81

I want to add the math, english, science, pe, history, and computer grades then find its average.

Generate Aggregation is the operator you search for.
