Can You Solve The Four Fours Number Puzzle?

Excited for the August 21 eclipse? Visit our Eclipse 2017 page to explore the science, history, and myths of the event. The Curiosity team will be viewing the eclipse alongside NASA in Carbondale, Illinois. Follow us on Facebook for live videos, trivia, and interviews on the big day.

Can you solve the four fours puzzle? You can use any mathematical symbols (but you cannot use numbers) to make the following equations true: 4 4 4 4 = 0, 4 4 4 4 = 1, 4 4 4 4 = 2, and so on. There is no last equation to solve; the goal of this puzzle is for you to solve as many as possible in a given time frame. If you're timing how long it takes you to solve this one, you must start at the first equation and go up in order, no skipping allowed.
