You must fill the rest of the numbers in a partially-filled number tower to solve each puzzle. The numbers generally start small at the top and get larger as you work your way up the tower, so the maths consequently gets harder as you work your way up the tower.\u003cbr\u003e\u003cbr\u003eThe number to be placed in each square is the sum of the two squares underneath it. Therefore if you have two adjacent numbers, you will use addition to find the number above them. If you know one of the two numbers under a square and the value in that square itself, then you will use subtraction to find the third number, so these puzzles are great for testing and developing both your addition and subtraction skills.\u003cbr\u003e\u003cbr\u003eAll answers are included at the back of the book - we hope you enjoy solving these engaging mental arithmetic puzzles, and developing your maths skills in the process.
