    Irrational numbers are ones with the square root of negative 1 as a factor, right?

      irrational numbers are numbers which are not a ratio of integers

      complex numbers, often called “imaginary” numbers, are ones with components of unit i =√-1

        complex numbers, often called “imaginary” numbers,

        Aside: mostly, but complex numbers are an addition of both a real number and an imaginary number: a + bi. It just happens that a can be 0, making it a strictly irrational number when b ≠ 0.

        Thus, the imaginary numbers are a strict subset of the complex numbers.
