Beremiz Samir, nicknamed The Man Who Counted or The Man who Calculated, was a fictitious Persian mathematician of the 13th century, created by Brazilian writer Júlio César de Mello e Souza.
The life and teachings of Beremiz Samir are the subject of the book The Man Who Counted, written by his equally fictitious friend Malba Tahan. In spite of his humble origins, Beremiz was well-versed in all branches of geometry and mathematics, a prodigious calculator, and a genial problem-solver. To him, numbers and mathematical concepts were living beings. He claimed that there are happy and good-natured numbers, sad fractions, grumpy multiplications, and sleepy tables.
Throughout his life, Beremiz used his abilities with calculation like a magic wand to amaze and entertain people, settle disputes, find just and wise solutions to seemingly intractable problems — and, ultimately, to secure his own happiness.
