The MULTITAB project is some code I wrote to: display the multiplication tables of numbers (between 2 and 9999), and also list perfect squares (up to 100).
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]
