Task: Question Answering
Input (English): Context: The nice thing about the Hewlett Packard calculators were that they used Reverse Polish Notation , which made operating so much easier . I used that calculator well into the 80 's , when it was finally stolen from my booth at the exchange . That calculator made me a lot of money finding the true value of options , despite it 's high initial cost . Things were so much easier back then . 
Question: What may happen if I owned a cheap nonbrand calculator instead ?
Output (English): It may take longer to obtain the result of a calculation .
