I'm completely new to looking at company financial statements for analysis, so please correct any misconceptions I have here. I'm having trouble with reading an Income Statement. I am looking at the Income Statements provided by Amazon between 2016 and 2019 using MSN.com (link will be provided), and I'm not sure how the Operating Expenses were calculated for 2016 (or any of the other years for that matter). My confusion makes further calculations even more difficult.
In 2016, Amazon's Gross Profit after subtracting Cost of Revenue from Total Revenue ($135,987) comes out to $47,722.0 million (so far, this makes mathematical sense). When looking at the Operating Expenses, it shows $131,801.0 million. This is where it gets confusing. The breakdown of Operating Expenses should be SGA and Research costs, which when totaled comes out to $43,369 ($27,284 + $16,085), which means that it should be Gross Profit ($47,722) - Total Operating Expenses ($43,369) = $4,353. I assume this is how I would do this?
But that's not it at all, the Operating Expenses are shown to be $131,801. Where did that number come from? This makes understanding how Amazon spent its $47,722 million Gross Profit on Operating Expenses confusing and just complicates the picture for me.
Hopefully, I explained the problem well enough.
Here is a picture of what I'm looking at with highlighted sections:

Any guidance would be greatly appreciated. Thanks in advance!
