3 Additional ways to extend the HP Prime Free  Lite
1. Use global variables with the Define statement  copy and paste
lineptm M*('X'L1(1))+L1(2) 2. Use global variables with the Define statement and merge two function's code copy and paste linept1pt2 ((L2(2)L1(2))/(L2(1)L1(1)))*('X'L1(1))+L1(2) , 3. Use global variables with the Define statement and function compositions  copy and paste pivmat pivot(SCALE(M1,(1/M1(R,C)),R),R,C) Code originally for calculator, Pro, and Virtual software as programs CLSlines and pivmat shown below. Using these defined functions in the HP Prime Free along with CAS variables, the CAS and HOME view, and default Application Library Apps for courses such as Finite Math. The function pivmat would allow you to easily check your manual calculations for Simplex maximum and minimums; matrix inverses; and systems of equations where the linear function could be used for linear supply and demand; linear cost, revenue, and profit; linear depreciation and host of other linear applications. Note; for some reason pivmat only worked on CAS view with HP Prime Free iOS. We used fraction conversion key in various places. Notice the goofy representation of zero. Used matrix editor to add M1.
