Alright, in math, you cannot find the square root for a negative number. In order to still work with negative square roots, the imaginary unit is used. For example: The square root of 4 is 2. If you try to find the square root of -4, you'll be left with 2√-1. That √-1 is referred to as an imaginary unit, or i, because the answer to that does not exist.
