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 .

(A). I may make more money trading options ..
(B). It may take longer to obtain the result of a calculation ..
(C). I may show off the calculator to my friends at the exchange ..
(D). None of the above choices ..
Answer the following question: What may happen if I owned a cheap nonbrand calculator instead ?
(B).
