Welcome to a brand-new selection of number square puzzles, the puzzle that will test your mental arithmetic to the max! The rules of number square puzzles are quite simple, and are as follows: - Enter the numbers from 1 - 9 once each into the puzzle grid, so as to complete the maths sums that read across and down the puzzle grid. - You must always perform your calculations from top to bottom, and from left to right. This means that you will not always follow strict mathematical order. What does this mean? It means that if, for example, you have a multiplication and a subtraction as the two elements in a sum, and the subtraction comes first, you must work out the result of that calculation before the multiplication. This is as opposed to'strict mathematical order, where you would perform the multiplication element before the subtraction element, regardless of order. - Each puzzle has just one solution There are three different levels of difficulty in this book: Easy, Medium and Hard. Easy puzzles give you two starting numbers, so there are seven others to place. With medium puzzles, there is one starting number, so there are eight others to place. With hard puzzles, there are no starting numbers, so you need to place all nine numbers. In addition, on average there will be more possible combinations of values that work for different individual sums for the medium and harder puzzles, so you may have to consider several sums at a time particularly with the harder puzzles to work out the correct options. There are 100 puzzles for you to tackle in this book, so if you want to improve your maths and ability to perform sums, or just fancy a fun maths related challenge, then this book of 100 number squares could be for you!
