Number Crossword Puzzles: 100 Cross-Figure Puzzles

Available in print on Amazon.

This book contains 100 cross-figure puzzles, the numerical equivalent of a crossword puzzle. As with a crossword, digits from one answer are shared with digits from other answers. However, unlike a crossword puzzle, the value of most answers are dependent on one or more of the other answers.

Each puzzle can be solved through a careful analysis of the clues, considering the numerical properties of each number in relation to its digits and the progressive elimination of the possible options.

An Introduction to Mathematics for Computing and IT Practitioners.

Available on Amazon Kindle and in print on Amazon.

There are a number of topics within Mathematics which have a direct relevance to Computing and IT. Some of these topics form the basis of how a computer processes data, some are used at a higher level to enable a program to perform a required function, and others are algorithmic and can be easily implemented within a computer program. This books attempts to bring together many of these mathematical concepts and present them in a way which is relevant to those studying ICT and Computing qualifications, and to those who would like to start to explore this subject for themselves.
