By Mathnasium | Added Oct 5, 2015

Now that it's October, we have blustery weather, fall leaves, and Halloween on our minds. We're celebrating all month with a fun activity -- Trick or Treat! Solve these five math problems using mental math “tricks”, tell us how you solved them, and bring into the center for a treat.

Happy Halloween!
