The programming language of both series is BASIC. It should be noted that the implementation of this language in these models of calculators allows you to write programs suitable for automating complex calculations. By its capabilities in calculations, CASIO BASIC far exceeds the computer version, in particular, due to embedded matrix operators, including: addition, subtraction, multiplication, determinant calculation, transposition, inversion, exponentiation, assignment of all elements to the same values, creation of unit matrices , permutation of rows, addition of rows, dot product of rows, insertion and deletion of rows and columns, combining matrices, transferring data from columns to lists (one-dimensional arrays), etc. Source
