I am an engineer, working on various algebraic and arithmetic problems frequently during each day. Like most engineers, I have a computer at my desk for doing the tricky stuff (ideally with tools like Mathcad or Mathematica). I thought I would get this calculator for the routine numerical insight stuff. It also remembers to stay in radians when you turn the power off (which many other "lesser" calculators don't). What a mistake! Lets say I have just calculated a result. Now I want to find the square root of it. On my trusty old HP-32S at home, I press the "sqrt" key. On this calculator I press "sqrt" "2nd" "ANS" ")" "ENTER" (5 keys). Basically the EOS system (which this uses) does not allow you to see intermediate results other than by going through the above rite. I think TI is hoping this calculator will replace my computer - no chance! I'm taking it back.Get more detail about Texas Instruments TI-83 Plus Graphing Calculator.
