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.
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

Thus, the imaginary numbers are a strict subset of the complex numbers.
Irrational numbers don’t have a predictable pattern to them. Think pi.
