In college my calculator did not have a function to translate from rectangular to polar co-ordinates. however I could do it just as fast as those with newer calculators since it actually involved only about three extra key punches and I understood how to do it.
In tutorial we would be given questions to work out among ourselves. Everyone did their own calcvs then checked each others. many times I just glanced at someone else's answers and told them it was wrong and they would ask how I knew so quickly. It was because I could visulaize approx what the answer should be whereas they were just plugging in numbers and writing down what the calculator said. Often it was obvious that, for instance, they had punched in 2 instead of a 20. they simply did not understand what was being done.
One instructor deliberatly arranged questions so that one did not need a calculator and told us that we could do it faster without one.
For instance the question would have you dividing 4 X 105 by 2 X 103. While those who took the instructors words to heart simply wrote the answer 200 other guys would busily punch it into their calculators, often with hilarious results. One question ended up with the above 400000/2000 to get the final answer and the guy next to me wrote down 80 and I told him it was wrong. He asked how I knew and stated the obvious "that's what my calculator said". I pointed out that 4 divided by 2 is 2 not 8 and received a blank stare.
Now back to Christophera. He likely will not bother with your questions since they do not bear directly on his concrete core / C4 coated rebar postulations and thus he could not care less.
