vi The wonderful world of math
vii
The word, the two . . .
For most primary and secondary students in Croatia mathematics is traditionally unpopular
subject. Many of them have experienced it as arid, boring tiresome and difficult, but there
is a rationally small number of students who see and feels mathematics as beautiful, exciting
and seminal. Reasons which still led to such views resides not within mathematics itself: they
are in curricula and programs shortcomings and inadequacy, in textbooks and within some of
the teachers.
One of the most prominent Croatian high school teachers and math textbooks authors,
Stjepan Skreblin, used to say that for the successful mastery of mathematics students did not
need special talent, but they should not only be exceptionally talentless. A good math teacher
will know how to interests his students about it, who will always anxiously expect and with
the joy of creating participate in solving math tasks and problems.
This book of math comics is on the trails of attempts to increase understandings and
interests for mathematics. It was created based on a multi-annual section of comics (back
page) in magazine for young mathematicians Matka. It is in accordance with decision of 1st
congress of Croatian math teachers about math popularization, and as idea illustration that
math is always around us, in different situations. It is modest contribution towards standards
achievements published in Standards for teaching math.
The Wonderful World of ”Math” can be used as introduction stories or problems in teach-
ing new subject areas or differently. Parents may use stories to better understanding what
their children have been taught. For that purpose at the end of the book, stories are listed as
Number systems, Divisibility, Equations and Inequalities, Percentage, Diophantine equations,
Algebraic expressions, Logical tasks, Dirichlet’s rule (condition), Geometry, Graphs, Combi-
natorics, Probability and Statistics, and Ingenuity.
Comics’ lyrics were developed as dialogs that lead the reader from one problem to another.
Tasks and problems are chosen as easier and more difficult, more or less easy formulated,
discussed and solved, which allows the young reader to develop experience for the richness and
diversity of mathematics problems. For the advanced reader, it will be a stimulus for solving
tasks as well as creating own.
The book is designed as adventures and puzzles of school group students. Author’s ideas
are portrayed and characters are revived by Ninoslav Kunc. Kunc is by modifying characters
and commenting together with introducing minor characters/icons into original story gave
extra dimension and atmosphere. His comments are humorous and ironic in a positive sense
and by themselves are giving more lifelike frames to puzzles.
Problems are integrated into the possible realistic environment, but every reader realizes
that they are imaginary, i.e. that such reality does not exist.
Fundamental problem ideas are authorized or spotted in listed literature, with special
ideas selection from math history. Fundamental idea elaboration, text shaping’s and comic
illustrations are solely authors creations.
viii The wonderful world of math
In Croatian, nor in world literature, there is not such comprehensive attempt to make
mathematical problems in the form of comics.
There are attempts to classically write stories/novels in which mathematical problems
are present and their resolutions are main characters marginal activities. One of such rarely
attempt is book Stripologikon of Apostolos Doxiadis, Christos H. Papadimitriou and Alecos
Papadatos, in which the story of a modern mathematical logic and actors of its construction
was told in the form of a comic. And that is all.
Comic book The Wonderful world of Math includes new problems selection and it is natural
continuation of published book Adventures and puzzles of the Matka kids fellowship, written
by Petar Mladinic and illustrated by Zrinka Ostovic.
Given problem-story is usually frame in which eventually mode solving need to think
of, together with introducing new conditions which can help problem-solving (or cannot be
resolved).
Towards end of the book there is story list created accordingly to math subjects. List serves
reader as potential solving direction but also to teacher as orientation for introduction stories
or problems in teaching new subject areas.
In the end, sources and references for stories inspiration are listed.
With their reviews, text corrections and advices prof. Sanja Antolis, prof. Jelena Gusic,
and mr.sc. Nikol Radovic helped substantially.
Mr.sc. Nikol Radovic with her proofreading’s solutions substantially improved this book,
while prof. Sanja Antolis and prof. Jelena Gusic with their problem solutions examination
eliminated great portion of potential uncertainties, but also suggested a series of more simple
solutions.
To all of them, I thank heart fully!
I am also thankful to readers whom will, reading and solving this puzzles, point out errors
or better and more beautiful solutions, which I hope will be implemented in next edition of
The Wonderful world of Math.

Dijete je vatra koju treba razbuktati, a ne posuda koju treba napuniti.
Aristotel
Ante, Ivan, Luka, Jurica i Danica ucenici su jedne zagrebacke skole i glavni su likovi ove
nase price. Slicni su djevojcicama i djecacima u nama i oko nas. Dobri su prijatelji, sportasi i
streberi, mangupi i intelektualci. I stalno im se dogadaju neke zanimljive zgode. A ako im se
i ne dogode, sami ih smisljaju i izmisljaju, i tako im nikad nije dosadno. A susrest cemo ih u
razredu, na ulici, u trgovini, u stanu, na trznici, u knjizari, na moru. . .
Uz njih cemo upoznati i jos neke ucenike iz razreda: Kresimira, Vinka, Tomislava, Petra;
profesore Matka i Eugena; susjeda Martina; trgovce Marka i Anu; Antinu baku Maricu i djeda
Antu; podvornika Jozu. . .
Sigurno cete zajedno s njima uspjeti rijesiti sve matematicke probleme, a mozda i sami
smisliti neke nove zadatke za neku drugu pricu.

Tko ima prednost? (Who has the advantage?)
Uvijek pobjeduje drugi igrac sa sljedecom strategijom:
drugi igrac precrta ostatak reda (nakon sto je prvi igrac precrtao od 1 do 9 kvadratica).
Prvi je poceo Ivan. U ovoj igri obojica su igraca pogrijesila. Prvo je pogrijesio Luka jer u
drugom redu nije isao do kraja retka, a onda Ivan jer u cetvrtom redu nije isao do kraja retka.
Dakle, mogli su igrati bolje.
Kako posteno podijeliti? (How to divide fairly?)
Tri su prijatelja putovala jos 11 dana i potrosila 11 000 eura - svaki po11 000
3eura.
Marko je imao 7 000 =21 000
3eura i od toga iznosa potrosio je na sebe
11 000
3eura, a na
Jerka preostalih10 000
3eura.
Petar je imao 4 000 =12 000
3eura i od toga iznosa potrosio je na sebe
11 000
3eura, a na
Jerka preostalih1 000
3eura.
Jerko je, dakle, ”posudio” od prijatelja10 000
3+
1 000
3=
11 000
3eura.
Marko i Petar trebaju podijeliti iznos od 11 000 eura, koji im je nakon putovanja dao Jarko,
u omjeru njihove ”posudbe”. Marko je ”posudio” Jerku 10 puta veci iznos nego je to ucinio
Petar.
Dakle, Marko treba dobiti 10 000 eura, a Petar 1 000 eura. Markov je zahtjev posten!
Kako razdijeliti? (How to apportion?)
Lopta je stajala 450 kn. Svaki bi Matkac trebao platiti 112, 5 kn.
Iz izjava Matkaca mozemo sastaviti sustav linearnih nejednadzbi gdje su j, i, l iznosi koje
su za kupovinu lopte dali Jurica, Ivan i Luka.
j + i + l = 450 . . . cijena lopte
j ≤ i + l . . . Jurica
2i ≤ j + l . . . Ivan
5l ≤ j + i . . . Luka
Iz prve jednakosti izracunamo redom i + l, j + l te j + i.
Dakle, iz j + i + l = 450 slijedi da je
i + l = 450− j,
j + l = 450− i,
j + i = 450− l.

5. Note about authors
Ninoslav Kunc roden je 1957. u Zagrebu. Tijekom svoje umjet-
nicke karijere objavio je velik broj stripova, ilustracija, a bavio se i
dizajnom, te animiranim filmom. Ilustrirao je brojne udzbenike za
osnovnu i srednju skolu koji su se tiskali u milijunskim nakladama,
vise prirucnika, rjecnika i drugih izdanja vezanih za obrazovanje.
Knjiga za djecu koje je ilustrirao toliko je da ih odavno ne zna
nabrojiti. Desetljecima je suradivao s mnogim casopisima za djecu
i mlade, ponajvise s Modrom lastom, Smibom i Matkom.
Ilustrator je iznimne osjecajnosti i prepoznatljivog stila. Jedan je od rijetkih ilustratora
koji svoj crtez, prozet humorom, zna pribliziti djetetu a da pritom nista ne gubi na likovnosti
i minucioznoj perfekciji koja je svojevrsni zastitni znak ovoga darovitog umjetnika.
Ilustrirao je niz poznatih djecjih klasika koji su neizbjezni dio lektire. Neke naslove, poput
Petrice Kerempuha Slavka Mihalica i Bon - ton Zvonimira Baloga, ilustrirao je u vise navrata
za razlicite izdavace. Svako od ta dva izdanja (objavljena po tri puta) nastojao je dodatno
likovno obogatiti, sto je uvijek poseban izazov za ilustratora.
Svoje radove Ninoslav Kunc izlagao je na mnogim skupnim i samostalnim izlozbama, a
dobitnik je i vise nagrada za svoj rad.
Svoju strip djelatnost Kunc je profesionalno zapoceo jos sedamdesetih godina u casopisu
Polet. Bio je clan kultne grupe Novi kvadrat koja je unijela dasak svjezine u tradicionalnu
strip scenu. Stripom se kontinuirano bavi sve do danas, a poseban izazov bile su mu serije za
najmladu publiku.
U suradnji s profesorom povijesti Petrom Bucevicem objavio je knjige 100 slavnih izreka
i Anegdote o slavnim osobama, a u izdanju udruge Strip forum objavljena je zbirka njegovih
stripova Najzabavnije Kuncutarije.
Ninoslav Kunc godinama ilustrira i oblikuje matematicke casopise Matka i Poucak.
U suradnji s profesorom Petrom Mladinicem smislja stripove koji krase zadnju stran-
icu Matke. Te matematicke zagonetke u stripu jedan su od njenih prepoznatljivih zastitnih
znakova. Ova duhovita serija, koja izlazi godinama, na koncu je zasluzila da bude malo dot-
jerana i objavljena u knjizi.

Petar Mladinic roden je 1950. godine u Zagrebu, gdje je diplomi-
rao matematiku na Prirodoslovno-matematickom fakultetu.
Njegov rad ima dugotrajan ucinak na poboljsanje odgojne i
obrazovne prakse. Kao voditelj Nastavne sekcije Hrvatskoga
matematickog drustva pridonosio je razvoju profesionalnih potreba
ucitelja/nastavnika, ucenika i studenata u formalnome i neformal-
nome svakidasnjem i cjelozivotnom ucenju i poucavanju.
Organizirao je vise od 150 predavanja, mnogobrojne radionice, pokrenuo Ljetnu skolu
Rudera Boskovica te Ljetnu skolu V. gimnazije i HMD-a.
Za profesionalne potrebe ucitelja, ucenika i studenata utemeljio je cetiri matematicka
casopisa: Poucak, Matka, Playmath i math.e te inicirao izdavanja knjiga u sklopu Male
matematicke i Matkine biblioteke.
Napisao je stotinjak strucnih clanaka, knjiga, udzbenika, prijevode knjiga te organizirao
na desetke radionica za nastavnike i ucenike.
Pridonio je razvoju sustava obrazovanja u matematickom podrucju kao clan Vijeca za
nacionalni kurikulum i clan Radne skupine za izradu Nacionalnoga okvirnog kurikuluma za
matematiku.
Godine 2011. prijavio je projekt V. gimnazije IPAQ Peta - afirmativna nastava i inovativno
poucavanje u gimnazijama u okviru HKO koji je realiziran s timovima cetiriju gimnazija: iz
Vukovara, Pakraca, Knina i Metkovica te Prirodoslovno-matematickim fakultetom iz Zagreba,
uz sudjelovanje 1 200 ucenika i 1 000 nastavnika.
Osmislio je i organizirao projekt dvogodisnjih okupljanja ucitelja i nastavnika matematike
(susreti i kongresi nastavnika matematike) na kojima su izlagali hrvatski nastavnici, kao i
najugledniji strani strucnjaci iz podrucja nastave matematike.
Utemeljio je hrvatski ogranak TTT (Teacher Teaching Technology).
Utemeljio je i vise godina vodio Geometrijske radionice HMD-a.
Kao nastavnik, a posebno kao ravnatelj V. gimnazije, aktivno je bio ukljucen u zajednicu,
osnazivao demokratske procese, toleranciju i solidarnost medu mladim ljudima i njihovim
roditeljima.
U slobodnom vremenu bavio se i sudenjem rukometnih utakmica. Prvi je hrvatski
medunarodni sudac koji je licencu postigao u Lijepoj Nasoj. Od 1993. - 1999. godine bio
je clan tzv. elitne liste sudaca IHF-a (International handball federation). Sudio je utakmice na
Olimpijadi u Atlanti, 4 svjetska prvenstva, 3 europska, 2 azijska i mediteranske igre. Sudio je
zavrsnu utakmicu japanskog prvenstva kao i tuniskog. Takoder je sudio 7 zavrsnih utakmica
europskih kupova, utakmice na dva svjetska kupa te prvi europski super kup. Na obiljezavanju
100 godina sporta u Austriji sudio je utakmicu izmedu zenskih reprezentacija Austrije i Svijeta.
Ukupno je sudio vise od 250 medunarodnih utakmica.
Odlikovan je Spomenicom Domovinskog rata 1990.–1992., odlicjem Red hrvatskog pletera
i dobitnik je nagrade Ivan Filipovic.
