Radical Dad Hat

This is a radical dad hat.  Are you radical?  Show your inner rebellious geek by wearing this hat.

A radical is the symbol for the root of an number.  Often it is a square root, but other roots can be designated by placing a number at the beginning of the symbol.

The square root of 9 is ±3, because 3×3 = 9 and (-3)×(-3) = 9.

The cube root of 27 is 3 because 3×3×3 = 9.

Of course, someone who “bucks the system” is also considered a radical.
