One of the trickiest riddles you’ll find is the one that reads:

Turn me on my side and I am everything. Cut me in half and I am nothing. What am I?

Still unable to come up with the solution to this riddle? Here’s the answer for you:

## Turn me on my side and I am everything. Cut me in half and I am nothing. What am I?

If you turn the number 8 on its side, you get the mathematical symbol for infinity.

If you cut the number 8 in half horizontally, you are left with a zero.
