= your phone number

There's nothing interesting about this. A gradeschooler could invent the steps to get this result, as it's all based on (80 *250)/2 = 10000.
I said amusing. I didn't imply that it was some life changing, supremely difficult math problem. It is pointless, and it is easy, but I have not seen it before and was amused. Sorry if you found that it was beneath you.
