How I use excel at work

Excel is my main tool at work , since I manage the accounting department in a Real state company,I need to keep track of my  Account Receivables , Accounts Payable , The Monthly Budget , Depreciation of tangibles and intangible Assets, Calculate interest for Mortgages, Calculate commissions for agents  and so forth. I really found excel as a major help in my position.  Despite the basic knowledge I have about excel I am so eager to learn a lot more and bring new ideas for my team at work  .
