Split - Boolean Algebra

[MrX]

What is the simplified boolean expression of: /A/BC/D+/AB/C/D+A/B/C/D+A/BCD+AB/CD?
Or you might prefer it like this: A'B'CD'+A'BC'D'+A'B'C'D'+AB'CD+ABC'D

I think the "prime" notation (the apostrophe after letters) means "not". Does the "plus" notation mean "and" or "or"? What is the definition of the "slash" notation?

Thank you!

However 4 dimensional problems can be hard to visualize that way.

Slash means NOT the directly following variable.
Product means AND
Sum means OR

The + means OR the / means NOT and remeber each group is meant to have dots between the letters which is AND but the dots are invisible.
