Make it make sense ?? You must be new to this forum, let alone life in general.
Even in elementary school, back in the 50s & 60s, things didn't make sense, especially in 4th grade when they started certain of us kids on that new math sh!t. This equals that and that equals this on a thursday afternoon, when A minus B was mailed out in a yellow lunch box. Even then, we weren't allowed to use any tools and hadda show the formulas we used to reach our answers.
