Answer:
well it really depends on how and what number you put for the n like I put 10 and so the way jane said it should be doesnt work because 10-6 just doesnt make sense and you could do it a different way but if you had do 10-6 it wouldve been in the negatives and it wouldnt have been 4 so in this case we have more choices so I would say jack is right because it is more reasonable to do 6-n=4 and instead of the n we put a 10
