Original Description:
 At first I could not get the calculator to come on so I replaced the batteries and it still did not work so I read online and the recommendations said to push the one and square root buttons and then it came on and said memory clear and then it said machine rest and then it said error.  I don't know how to use this calculator and I am not sure of what needs to be done after being reset.  Please only buy if you know how to work because it will not come on with just pushi...ng on button, it has to be reset.  It has some scrapes and scratches and also the case shows wear.  Please see all photos.
