Aelfwine is correct that Tolkien did not have a calculator and I expect that he did the calculations by hand, long division, etc. https://en.wikipedia.org/wiki/Long_division
He may have also used a slide rule (https://en.wikipedia.org/wiki/Slide_rule) or Log Tables (https://en.wikipedia.org/wiki/Mathematical_table).
Finally, I doubt that he would have owned one of these, but the University would have had mechanical calculators (https://en.wikipedia.org/wiki/Mechanical_calculator) so he possibly could have used one, but very unlikely as they were not simple to use.

Thank you Carl, excellent work. I will use these to update my eBook edition and my working copy of the hardcover.

I'm continuing to work on my paragraph referencing scheme (less important here because of only a single pagination but still useful for certain work) and I'll map the errata locations to that once I'm done.
