# Mathelona

Welcome to MATHELONA and our unique series of number puzzles which are now available in two different formats, pocket book and e-book.

Like many new ideas, our popular number puzzle started life on scraps of paper and nearly became a wooden board game many years ago, but eventually it progressed to become an app in 2011.

It now regularly appears as a fun public challenge posted on Twitter and sometimes as one of our daily challenges at the 7puzzleblog.com number puzzle page.

The MATHELONA Pocket Book

Our very latest publication is our MATHELONA pocket book of holiday challenges.

The first in our series, Vol.1, contains 28 different number puzzles and has primarily been designed for children to use at home, ideally with parental involvement, to improve their arithmetic skills.

Our challenges are perfect to sharpen logic skills, concentration and resilience.  They are, of course, also attractive as a good test for the puzzle enthusiast.

A typical MATHELONA challenge can be seen below.

The MATHELONA pocket book is a useful travel companion on long journeys in the car, bus, train and aeroplane.  The challenges are also great to try during holiday periods so children can keep on top of their mathematical thinking, whether it be in the caravan, at the holiday cottage, on the beach or by the pool.

Retailing at just £3.99, you can invest in a copy either by simply sending us an e-mail at paul@7puzzle.com or by buying directly from Amazon by clicking the link.

The MATHELONA e-books

Our venture into the world of e-books began in 2016 with the publication of MATHELONA Volumes 1 & 2.

As with our pocket book series, the 25 Bronze medal challenges in Volume 1 and 30 challenges in Volume 2 of our e-book require players to utilise a group of 12 numbers to solve the puzzle. They are not allowed to deviate from these 12 numbers during a particular challenge.

A different combination of numbers appears in each challenge (to arrive at a variety of target numbers) and will always be in the range 0-9. The three target numbers to reach in each challenge will be in the range 0 to 18.

MATHELONA Challenges

As a taster for you, a typical MATHELONA challenge is re-produced here. Why not have a go at correctly arriving at the various answers?

• Insert 1 1 1 1 2 2 2 3 3 4 5 6 into the gaps below to make the three lines work out:

◯  +  ◯   =    3    =   ◯  –  ◯
◯  +  ◯   =    4    =   ◯  ×  ◯
◯  +  ◯   =    5    =   ◯  ÷  ◯

Answers to all questions are provided at the respective books and e-books. Have you solved this one yet?

Skills Required

This type of arithmetical exercise is perfect for children (and adults) aged 7 years and above as it is essential they have a good basic knowledge of the four operations when progressing through primary school.

MATHELONA reinforces this in a fun and challenging way and you will undoubtedly see their skills improve the more challenges they try.  This traditional method of learning also enables confidence and creativity to flourish throughout their educational life.

Purchase for School or Home

Whether you wish to invest in our books and/or e-books with the aim of improving arithmetic and logic skills in school, or simply for a bit of number fun at home, it has been widely recognised that attempting our MATHELONA challenges can enhance problem-solving, reasoning, concentration and mathematical resilience as well as encouraging independent learning.

Simply click this Amazon link to order a copy for £3.99 plus P&P.

Private Tuition Sessions

It’s also strongly advised that private maths tutors use MATHELONA as part of their sessions, either as a fun starter, confidence-building exercise or even as part of a diagnostic screening procedure. Tutors have learned so much about their students when observing them tackling the various challenges.

Although originally designed for the Kindle, the MATHELONA series of e-books can be played on smartphones and tablets but you must firstly download the free Kindle app.

Click this Volume 1 link to arrive at the appropriate page, and similarly for Volume 2, to enable you to make an investment in these great educational resources. Alternatively, visit the Amazon website and type MATHELONA in the search bar.

Each volume costs just 99p in the UK and the equivalent of US\$1.49 worldwide.

Future Editions

Volume 2 of our series of pocket books has already been developed, containing 28 further challenges, and we hope it will be published sometime during 2017.

Enjoy MATHELONA!
