Question: How do i use keywords in open math equations as the words not the symbols they represent?

Info: I'm trying to write up a proof in open Math, it goes well until I try to say something like "Let A and B be sets" and end up with "Let A ^ B be sets" it sees the "and" and puts in the and symbol, but I want the word. So does anyone know how I can use keywords as plain words in open math?
