Similarly all the numbers that have i in them are the imaginary numbers. Of course the two numbers must be in a bi form in order to do this comparison. Formal definition of homotopy type theory gigabit ethernet full duplex is actually 2gbit sec counting both ways. Equality of complex numbers.

The equality relation among the is determined as consequence of the definition of the complex numbers as elements of the quotient ring ℝ x 2 1 which enables the of the complex numbers as the ordered pairs a b of real numbers and also as the sums a i b where i 2 1. 3i 4i i sqrt 9 etc. This way a complex number is defined as a polynomial with real coefficients in the single indeterminate i for which the relation i 2 1 0 is imposed.
