Heading back in time

I never thought I'd be excited I paid attention in Algebra class all those years ago (let's see, 7th grade Algebra, 8th grade Advanced Algebra, some year in high school, and finally College Algebra) but it's finally paying off.  The few days I've been working on costs analyses for my facilities/companies at work and while I have final numbers on multiple sales and cost reports, the numbers are pulling from different spots in our system.  After an in-depth meeting with my bosses last week (each Sales Accountant got a personalized meeting based on our specific customers and locations, which was super helpful for someone with only 5 months of Sales Accounting under her belt!), ultimately we need to know what report is using what calculation. 
Enter those wonderful handy dandy math skills that I thought would be useless once I hit the real world.  After 2 days, I have most of the reports decoded.  I'm not entirely sure each report is illustrating exactly what we want it to, but at least I have answers for my boss when she asks how we came up with a certain customer cost, sales price or adjustment.  I even went old school when completing my calculations, pulling out the pencil (ok, it was black pen) and paper solving my equations by hand.

I'll leave the hard part making sure the figures are reported in the right spot up to management and our system programmer.  For now I'll just be happy that I retained something besides boy band lyrics from my teenage years.
