The MULTITAB project is some code I wrote to: display the multiplication tables (from 2-9999) of numbers, and also perfect squares.
TIRAD on the other hand: turns a number into its radical form, for example: √80 will be printed in radical form as 4√5.
The program MATRIXIT easily solves, and shows all the steps to get an augmented matrix in reduced row echelon form (rref). To input, put a 3x4 Matrix in using 2nd+Matrix > Edit > [A]. Original Matrix has to be [A]
