What is another word for imaginary number?
Pronunciation: [ɪmˈad͡ʒɪnəɹi nˈʌmbə] (IPA) 
An imaginary number is a concept in mathematics that is used to represent square roots of negative numbers. However, this term is not the only way to describe this concept. Alternatives include complex number, mathematical imaginary, and even fictitious number. As the term "imaginary" can sometimes be misleading, some mathematicians prefer using the term "complex" number, as it suggests a richer and more abstract concept. Another synonym used by some mathematicians is "pure imaginary," which emphasizes that only the imaginary part of the number is non-zero. Regardless of what term is used, it is important to remember that imaginary (or complex) numbers are a foundational concept in mathematics and have applications in a range of fields, from electrical engineering to quantum mechanics.
