    which part is confusing? Ok for starters I switched around the order of the sentence. I put the result which was cannot watch movie at the end of the sentence So basically i rearranged the sentence so that the 2 conditions are in the beginning unless accompanied by an adult is another way of saying not accompanied by an adult

    okkk we need 2 conditions in order to not be able to go to the movie 1) under 18 years of age 2) not accompanied by a parent Under 18 years of age is in a postive form p=under 18 years of age Not accompanied by a parent is in a negative form ~q= not accompanied by parent q=accompanied by parent
