This calculator is great for degree students in a budget as it will solve linear, quadratic, cubic...equations as well as carry out operations on matrices amongst other things. When you are solving 3rd order ordinary differential equation in an exam, this calculator might be the difference between a fail and a pass or even a higher grade. It is a time saver when you are assessed on your ability to solve differential equations. This price is standard and not really a bargain. Did not vote either way.
It's not that this calculator is very different. A Standard calculator works just fine but will be dependent on the student on how he uses it. This calculator makes things as easy as legally allowed. I purchased this for GBP 20 on Amazon. Brand New
I can tell you clearly aren't a maths teacher.
Graphical calcs are great for checking quadratics equations. Some now can transpose formula aswell as giving the working out. No good in an exam but great when you're learning on your own.
Both the calculators you mention are the ones that the my son's school recommend and sell.
