Hewlett Packard 48G graphing calculator. I am the original owner of this item and it is in perfect working condition. Great for grade 12 or university/college. I have all the user guides, manuals etc. This calculator can store equations, comes with equations library, units conversion functions, plot equations, and tons more. You can even put little games on this. It comes with minesweeper for when you are bored in class. Some of the headings in the manual: matrices and linear algebra, binary arithmetic and number bases, date time and fraction arithmetic, solving equations, calculus and symbolic manipulation, statistics and data analysis, plotting etc. I found the equation libraries invaluable (and you can add your own equations too).
