Sharpen your pencil and get ready to boost your brain with this
brand-new numbers game. To solve each puzzle, fill the 16 cells
with the numbers 1 to 16 using each number only once. Each puzzle
has just one solution, and uses math you learned in grade school:
addition, subtraction, multiplication, and division. The games,
which all call for logic, imaginative thinking, intuitive
elimination, and sheer persistence, are grouped in three
categories, and range from relatively simple to super-challenging.
The author's spirited instructions and sample puzzles walk you
through the basics; clues for some puzzles provide what might be
necessary encouragement. With 14 bonus puzzles aimed at children
and those who want to start with the ultra-easy, these 150 puzzles
will keep you thinking whether you're a student honing your math
skills, a puzzle-lover looking for a challenge, or someone who just
wants to get those brain synapses snapping!
