While most of us will head straight to our phone calculator app for the simplest of calculations, at least one kid has shown no need for that.
In a video posted online, a boy is seen to be swaying and moving his hands as he is rapidly given numbers to add and subtract.
The clip has been viewed more than three million times.
It is unknown where the boy is from, though we wonder if it was staged?
Most netizens were amazed by the boy’s talent with many praising his ability to calculate sums up on the spot.
“Did someone check if he is faster than a calculator?” read a comment.
Some questioned his method, with some likening his actions to someone having an epileptic fit.
“I never trembled like this when learning how to use the abacus,” wrote one such netizen.
Another netizen asked: “Would he be able to do the calculation should his hands not move?”
Well, whatever works to get the correct answer, right?
However, some were dismissive of the boy’s abilities.
“It’s fine if you don’t have his talent. The app on your phone is free,” read one comment.
