Microsoft Excel and Word work - repost 2

Excel part: I have 10 excel spreadsheets. I need someone to 1. delete some of the data based on my instructions. 2. analyzed the data, it's very very simple, basically just arithmetic. But you must be very familiar with the function of the Excel and maybe basic Excel programming to finish it in shortest time. I believe if you are an expert in Excel and very familiar with it, you can finish this job in 2 or 3 hours Word part: I have approximately 100 to 150 equations from a word file, they're in the format of screenshot. I just need someone to type down these equations based on the original screenshot without mistake. Just like I said, this job will be really easy if you really know it.
