Outstanding! These little arabian tales about a man that solves mathematical puzzles and curiosities, kept me wishing I had studied more Maths. It is easy to follow and very enjoyable! I read it when I was little and still remember most of the riddles. These type of books always makes you feel a bit smarter.

Este libro de "El Hombre que Calculaba" es uno de mis favoritos y aunque ya lo he leído, siempre es agradable volver a leer algunas partes.

El libro narrado por Malba Tahan, un musulmán de Bagdad, habla de los momentos que vivió a lado del hombre que calculaba: Beremiz Samir quien en su paso por Bagdad se hace de fama por su capacidad matemática para resolver problemas de toda índole.

La forma en que se narran las historias asociadas a problemas matemáticos es bastante amena y l
The man who counted is a book of two guys named Beremiz and Honok.These two on there adventure run into a lot of problems.Beremiz then solves it in a way that will make evryone happy.When he solves it,he will sometimes get a reward,something he wants,or nothing at all.Until he is put to a challenge,he had to take 7 challenges.If he solved them all,he would get whatever he wants.But he refuses the offer and says,"I would rather marry Telassim."So they gave him a final challenge, if he solves it ...more
This is a lovely little collection of mathematical tales told by a fictional Arabic scribe in around the 14th century Baghdad. There is a narrative connecting the stories as the narrator befriends Beremiz Samir, a wise Muslim mathematician also known as the Man Who Counted.

In each story, Beremiz wows the people that come in contact with him by his computational power, logic, and knowledge of the history of mathematics. Most of the stories are great mathematical logic, geometric, or computationa
An interesting group of math-y episodes. Nice poetic (translated from the Portugese---the author is Brazilian. Takes place in Baghdad in the middle ages. About a self-taught mathematician, and how he wows those around him by solving difficult (but contrived) problems. I'd have liked more of a plot. I was pleasantly surprised by how many of the little vignettes I was not familiar with. But they were contrived, and some of them poorly-enough posed that it felt like it wasn't really a mathematician ...more
Wonderful and playful book about mathematics. It is full of quirky and intriguing mathematical properties all presented through the eyes of the fictitious Bermiz Samir as he makes his travels in the middle east. Do look for the problem of dividing the camels, it is a treat.

My mother obliged me to read this when I was a kid, and I really wanted to read it, for she said it was good, but the guy kept doing maths! I was shocked that I couldn't find the plot, only situations that led to maths. Frustrated kid, hahaha.
Who would have thought you could enjoy a book all about "mathematical adventures"? Well, this is an excellent one. It was a fun, quick and easy read.

I loved this book! And that's saying somethin' since I HATE math!! (at least, I hate secular math)

Although many seemed to have like this book, somehow it didn't work for me. I started it, put it down. Started it again, put it down again. Maybe I read it at the wrong moment, I just don't know. Maybe it's because I have a Mathematics degree and there's not too many surprises, although the riddles are interesting. Or maybe it's just because there is no real plot and the book is just a connection of unrelated stories that all look similar. Maybe I should try reading it again some other time but ...more
Tijdens een reis van Samara naar Bagdad wordt Beremiz Samir, een jonge man met een buitengewoon wiskundig talent, voortdurend geconfronteerd met mensen die een beroep op hem doen om allerlei rekenkundige dilemma's en ruzies op te lossen. Spelenderwijs worden de problemen telkens weer uit de weg geruimd en weet Beremiz zijn publiek te vermaken met allerhande wiskundetrucjes en spelletjes. Voor elk schijnbaar onoplosbaar probleem heeft hij een oplossing, vaak zelfs zo eenvoudig dat de lezer zich z ...more
Ricordo che da piccola l'avevo abbandonato; stavolta è andata molto meglio.
Non è una lettura particolarmente avvincente, ma questo non è necessariamente un male, si presta ad essere letto in più tempi in quanto i capitoli sono abbastanza indipendenti tra loro.

Ogni capitolo propone un problema logico-matematico inserito nella bellissima cornice narrativa ambientata a Baghdad sotto il califfo al-Mutasim. A narrarci la storia è uno scriba amico del protagonista Beremiz, l'Uomo che sapeva contare. I

A good collection of math puzzles wrapped up in an Arabian Nights style quest tale, set around Baghdad in the 13th century, so serving additionally as a middle east history and geography primer. Each problem is posed as a moral quandary, and each solution illustrates a virtue. Malba Tahan is a pen name of Júlio César, who was a teacher of mathematics in Brazil ( and, for me, shares a style with countryman Paulo Coehlo.

Recommends it for: those who like math and logic puzzles
This is one of the quirkiest books I've read. If you are one to hit the papers first thing in the morning to solve Sudoku, Kakuro, Mind bender, then go ahead and read this book. This is definitely your kind of book.

The Man Who Counted is about a mathematician Beremiz Samir and how he solves different problems with his knowledge of mathematics. Sort of like your Arabian Sherlock Holmes, just that the problems may not be that gory in nature. More like fights over camel distribution and such. He is
There is a quote on the cover of my edition which immediately made me think "Oh no, this can't be good".
The quote is by Paulo Coelho, and it says "This book has helped me write "The Alchemist"."

What you need to understand is that I really disliked The Alchemist. (You can read my review if you like.) And not for story reasons; I hated the writing. I felt lectured, I felt like the author didn't trust in his readers. And I was put off - if that were to happen in a book about mathematics, I could p

This was the very first book I really enjoyed reading.

I was about eleven years-old when Beremiz opened me that new world, and that's why I consider loaning the book to every kid I know - if you're a grown-up, go and buy it yourself ;) I'm sure you will love this playful, beautiful,upbeat, precious book.

"O Homem que Calculava" (I'm proud it's by a Brazilian author) proves that's no reason why someone should be afraid of those great friends of ours called "numbers". Or "books".

James Miller
Capturing something of the flavour of the 1001 nights and mixing in a healthy dose of mathematics. The maths is never hard in the sense of requiring deep knowledge of difficult stuff, rather it plays with logic and applications of basic arithmetic, so that you find yourself having a stab at the puzzles (I especially liked the find the liars, find your coloured disk, and divide your camels).

I'd recommend this to anyone with a taste for the fiction of the orient and an enjoyment of puzzles.

I hated math in school but loved languages and literature. My father loves math and sciences, and always tried to make me see the beauty in numbers: to me as a teenager numbers were boring and useless.

He suggested then that I read the book The Man Who Counted written by Malba Tahan. My father thought this book will be great for me: I liked to read, and the author has a charming simplicity to explain math and how to apply it to everyday situations. Win-win situation.

I read it in Spanish first, a

The collection of tales is wonderful, and reading this book is enough to spark an interest in math. It's entertaining to read.
What bothered me though was that the book is filled with translation and history mistakes. They don't degrade the story itself for the typical reader, but they irritated me personally. Also, such a story could have ended in a better way. The last chapter is so out of context and it reads like a religious pamphlet.
Alan Marchant
The Man Who Counted is a composite historical fantasy in the style of the 1001 Nights, but carefully expurgated for a devout Muslim audience. The central theme is praise for Islamic contributions to Mathematics. This should work for readers with elementary arithmetic and logic ability. But for more talented math students the puzzle stories are too simple, undermining both the educational and Islamic didactic messages.
The man who counted by Malba Tahan is about a man named Hanak who is traveling to Baghdad when he meets a man named Beremiz. Beremiz is a mathematition who is also going that way. They decide to go look for work toether. On the way they meet a man named Salim Nassier. When they bring the important man to Baghdad, they are given important jobs. So the book basically shows their adventures together. At the end of the book he settles down and marries Sheik Izzid's daughter Tellassim

Maurizio Codogno
Il sottotitolo di questo libro, "una raccolta di avventure matematiche", è un po' fuorviante. In realtà ci troviamo di fronte a una serie di problemi matematici sotto forma di racconti, un po' come Le Mille e una Notte: il tutto viene ambientato a Baghdad nel periodo del Califfato. Beremiz Samir, l'Uomo che Sapeva Contare, è in primo luogo un buon musulmano, ma anche una persona che ama i numeri sotto tutte le sue forme. I problemi che dovrà via via risolvere sono tutti piuttosto noti, ma devo d ...more
O facto de ter demorado tanto tempo a ler um livro de 200 páginas é um bom indicador da falta de interesse que me despertou. A escrita é anódina e os poucos acontecimentos apenas servem como pretextos para apresentar curiosidades e enigmas matemáticos, a maioria dos quais bastante básicos, ou não fossem dirigidos a um público juvenil (mas não estou a ver o meu filho adolescente a ler isto...). Enfim, não me conquistou.

The book The Man Who Counted is about two travelers named Hanak and Beremiz. Hanak is telling this story. Beremiz iz a great mathamation. These two are traveling and are Beremiz is solving all of these everyday dilemmas. Like the camels dilemma, melons dilemma, and dinner bill dilemma. ONe day Beremiz has the toughest challenge in front of him. He has to solve 8 very challenging dillemmas. I the end he conquers them all and is reward the princesses hand in marrage.

Read this decades ago when I was in middle school - I know, I was (still am) a geek. Was fascinated by the puzzles, and glad to see a mathematician portrayed as a hero. Just re-read the book, and the wonder and sense of discovery that I had experienced back then came back anew. Highly recommend.
The man who counted is a book about this manamed hanak in his village that soon met Beremiz. This book has Beremiz being a really good counter and can count things just by looking at them. As the two were traveling to Bagdad, they ran into some problem but being the man who counted he solved them easily. In Bagdad he solved many more dilemma and he later became a man that works in the goverment. he soon went to a palace to tutor the kings daughter Talassim. For all of the delimmas Beremiz solved ...more
Aku baca yg versi bahasa Indonesia dengan judul: Laki-laki Penghitung. Buku yang sangat menarik, walaupun jelas2 aku tak jago matematika. Setelah baca buku ini, matematika jadi tampak menyenangkan dan jadi solusi bagi banyak permasalahan yg tampaknya tak memerlukan matematika sekalipun. Dengan menampilkan seorang lelaki dari era kesultanan timur tengah, tiap bab buku ini menampilkan satu persoalan yang kemudian dipecahkan secara matematis oleh sang tokoh utama.

The man who counted was about two guys that traveled around and solving dilemmas. Beremiz is the main person who solves most of the dilemmas. Hanak was the narrator and Beremiz and Hanak met in the same first chapter of the book. They met when Hanak was traveling from one city to another and met where a guy was counting. The dilemmas were mostly about math and some of them were the camels, loaves, the four fours, jewlry and logging. At the end of the book Beremiz completes seven chalenges and i ...more
