This African man could count only up to 14 with his fingers.
American scientists took him to Virginia as a slave and tested his unusual mental ability.
After testing his brain, they discovered that he was exceptionally skilled at solving complex mathematical problems. People started calling him “The Human Calculator” and “Genius John.”
One day he was asked this question:
“How many seconds are there in 70 years, 17 days, and 12 hours?”
He listened to the question for just 2 minutes and immediately replied:
“47,304,000 seconds.”
Everyone was shocked because a normal human being cannot calculate this so quickly.
Later he was given another problem. He thought for only a few minutes and answered:
“2,210,500,800 seconds.”
Scientists could not believe it. His mental ability amazed the whole world.
