What are the relational and boolean operators you used in your example? if the boolean operator is changed, does that change your outcome? if so, how?

you can only change it if your real name or personal information was in it. and if so you would need to contact them directly with a username change request.

answer: a, c

divide any of the y values by x values and you will always get 3 is the most simple way i can put it for you.

storage maybe?

are there options?
