I remember my nanny when I was a kid. She never went to school. She couldn’t identify numbers nor be able to answer if you’d ask her 1+1. Why she couldn’t even write her own name. But when it comes to money, she knows how much will be her change when my mom asked her to buy something from the store. She’d also know if a single centavo would be lacking from her change.

There’s a lot of Filipino mathematicians who won various math contests all over the world. But did you know who set the world records when it comes to mathematics? He was named as the fastest human calculator of the world.

Alexis Lemaire, 27 years old sets the record when he correctly calculated an answer of 2,407,899,893,032,210 from the possibility of 393 trillion answers at London’s Science Museum. He found the answer to the 13th root of a random 200-digit number in 70.2 seconds by sheer brain power - beating his own world record of 72.4 seconds he set in November.

Lemaire broke the record in the Science Museum’s History of Computing gallery. It is the home of Charles Babbage’s Difference Engine No.2, the world’s first mechanical calculator, designed in the 1840s.
