Not all reviews, however, were negative. Nader Elhefnawy at "Strange Horizons" described the book as "an interesting experiment". He said that Pohl deserves the credit for "capturing Clarke's voice", and that Clarke also deserves credit for doing something completely different. While he would not recommend the book to readers new to Clarke's work, Elhefnawy said that fans would not regret reading the book. Mark Yon at "SFF World" said that while this is not one of Clarke's best works, "it is still very good". He said that even though it is a collaboration, the book is still recognisably Clarke, "with the same humour, the same enthusiasm, the great flashes of inspiration, the big ideas and the same curious positivism that underlines most of Sir Arthur’s work. ... There is a joy throughout here: a joy of learning, of opening up new opportunities and experiences, and a love of mathematics and science." Michael Berry at the "San Francisco Chronicle" said that the novel does a "stellar job of conveying some of the intellectual fun that can be had by manipulating math." He said that Sri Lanka, Clarke's home for most of his life, is brought "vividly to life", and that despite some minor flaws, "The Last Theorem" is a "fitting valedictory for Clarke, one of science fiction's most acclaimed authors, and a reminder of Pohl's great relevance to a genre he has championed for more than 70 years."
