From a multibillion-dollar cab ride, to a slice of digital history, this is The Week in Numbers.
$5.4 million is this week's price for... nothing tangible.
That was the winning bid for the original source code for the World Wide Web, as written by British inventor Tim Berners-Lee.
It was sold as a non-fungible token by auction house Sotheby's.
The buyer gets to boast about owning a bit of digital history. They definitely don't get to own the Web itself.
About $68.5 billion was the value put on Chinese ride-hailing giant Didi after its shares started trading in the U.S.
That left founder Cheng Wei with a personal stake worth about $4.45 billion. Not bad for a man who once worked as assistant to the boss of a foot massage firm.
Renaissance Capital Principal Kathleen Smith says Didi is worth the big numbers:
"It's bigger than Uber. It's one of a dominant player. And it looks like the valuation that was placed on the company was reasonable."
$70 million is the fine for providing false or misleading information to customers and other "systemic" failures. Or at least it was for share trading app Robinhood this week.
The popular platform for retail investors has faced numerous probes of late.
But analysts say the latest fine should clear the decks, and leave it free to press ahead with an IPO expected to value it at around $40 billion.
$715 billion is how much the U.S. House of Representatives voted to spend on transport and water infrastructure.
That funds all kinds of projects, including fresh tunnels linking New Jersey and Manhattan in New York.
Democrats hope it's the first step toward sweeping infrastructure legislation.
And 270 is how many jets United Airlines just ordered from Boeing and Airbus.
The mega-order is the carrier’s biggest ever, and valued at over $30 billion - though United probably got a big discount on list prices.
Analysts will hope it’s a sign that confidence is returning to the battered air travel industry.
