  • Imaginary Unit
    A mathematical symbol representing the square root of negative one, enabling evaluation of square roots of negative numbers.
  • Square Root
    A value that, when multiplied by itself, yields the original number; for negatives, involves the imaginary unit.
  • Negative Number
    A value less than zero; its square root is not real and requires the use of the imaginary unit.
  • Radical
    A mathematical expression involving a root, such as a square root, often used in simplifying negative roots.
  • Real Number
    A value that can represent a distance along a line; excludes roots of negative numbers.
  • Imaginary Number
    A number formed by multiplying a real number by the imaginary unit, used to express roots of negatives.
  • Simplification
    The process of rewriting an expression in a more concise or standard form, especially with radicals and imaginary units.
  • Factorization
    Breaking down a number or expression into products, often used to separate negative signs under radicals.
  • Radical Expression
    An expression containing a root symbol, which may include real or imaginary components.
  • Whole Number
    A non-negative integer, often written before the imaginary unit in simplified expressions.
  • Standard Form
    A conventional way of writing expressions, such as placing the whole number before the imaginary unit and radical.
  • Mathematician
    A person who studies or specializes in mathematics, responsible for introducing the imaginary unit.
  • Root Symbol
    A notation used to indicate the extraction of a root, such as a square root, in mathematical expressions.
