The first step of that process usually takes the longest. In 1748, though, when Euler published the Introductio in analysin infinitorum, most mathematicians and scientists were quite good at taking square roots by hand, but logarithms required difficult analysis or a book of tables. With Napier's system, on the other hand, this operation took just a few minutes. First, the astronomer would look up the logarithms of each factor. Next, he would add these logarithms together, and then would find in the tables the number for which this sum was the logarithm (called the antilogarithm).
