What do you call these calculations?
Can you at least tell me what is the name of these calculations, so I can research the proper way to get them done? I understand what they are doing and I understand what you are showing me, but correct placement of parentheses and such is what is fouling me up. Is this algebra? Is there an order of operations?
While doable, this calculation for my site sounds like it will be very long. Is there anything I could do to simplify my site, based on what you know?
