Starting point for input of coefficients.
Loop–control value: loops from 1 to 12, one at a
time.
Stores control value in index variable.
Starts the input loop.
Prompts for and stores the variable addressed by i .
Adds one to i .
If i is less than 13, goes back to LBL L and gets the
next value.
Returns to LBL A to review values.
This routine inverts a 3
Calculates determinant and saves value for the
division loop, J .
Calculates E'
determinant = AI – CG.
Calculates F'
determinant = CD – AF.
