No matter how efficient you are in the workplace, you're going to feel a bit inadequate after seeing this video.

This office-working woman has the power to blaze through spreadsheets and numbers armed only with a portable calculator. Watch as she types in and totals numbers faster than you can even imagine. In the middle of the clip, a timed showdown takes place, and this woman was easily able to blast through a full page of math in less than two minutes, accurately calculating the total number 990,974,372,328. 

If you're not already impressed, watch as she shows off the ability to fully converse while doing this advanced math. Even this is nothing compared to what she does next: This math wiz goes at it double-fisting, knocking out numbers with both hands and two calculators!
