A convenience store in New York is trying to encourage people to use their math skills.
The owner’s son 20-year-old Ahmed Alwan, has been posting videos where he asks customers simple math questions. If they answer them correct they have FIVE SECONDS to grab as much stuff as they can.
He told news reporters he started doing it as a fun way to help out people in his community. But he also hopes kids see the videos, and it inspires them to learn.
