In a feat of intelligence that looks more like the impossible, a group of girls from India perform mental math that seems to defy the odds.
As an unknown person asks them math equations, and performs them on a calculator, the girls beat him to it, figuring out the equation using just their brains and quick-moving fingers. But they aren't using their fingers to count. They're using them as beads on an imaginary abacus, or a math tool, that helps people solve equations without using calculators.
They answer problems such as ...
Minus 1478-547-358-199 ...
Then ish gets real.
Let's just say they figured out the correct answers before I was done typing the equations.
You go, girls!
