TI-30X Pro MultiView and TI-36X Pro (2011): In addition to the features TI-30XS and TI-30XB MultiView, it features a solver, availability to calculate matrices, vectors, complex numbers and convert different units. The TI-36X Pro is the American and international version of the European model, the TI-30X Pro MultiView.
The 35s stores complex numbers as single values, which can then be operated on in the standard ways. The above example of adding 12 + 34i and 56 + 78i then becomes: 1 2 i 3 4 ↵ Enter 5 6 i 7 8 +. On the 35s, the number of functions able to handle complex numbers is limited and somewhat arbitrary.
EL-506W adds matrix calculation, list calculation (max 4 lists, 16 elements/list) to EL-520W, for total of 469 functions. EL-500M is a single line version of EL-509W, which contains only the dot matrix line. Dot matrix line only shows 11 characters. Memory register is reduced from 9 to 1.
In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, if a {\displaystyle a} and b {\displaystyle b} are real numbers, then the complex conjugate of a + b i {\displaystyle a+bi} is a − b i . {\displaystyle a-bi.}
under which addition and multiplication of complex numbers and matrices correspond to each other. For example, 2-by-2 rotation matrices represent the multiplication with some complex number of absolute value 1, as above. A similar interpretation is possible for quaternions [77] and Clifford algebras in general.

A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i 2 = −1.
