The number of black dots in each grid increases by 1 each time, starting with the top left grid and working to the right, top row then bottom row.

Adding the three numbers in each square together gives the numerical value of the letter at the centre of each square.

The Hammer = 1, the File = 3 and the Axe = 5

The value at each corner of the diagram equals the difference between the sums of the numerical values of the letters in the boxes adjacent to the corner.

Working from left to right, top row then bottom row, the first grid contains a sequence of 2 black dots and a sequence of 3. The next grid contains one of 3 and one of 4. Continue, adding 1 to each sequence every time.

In each diagram, the numerical value of the left hand letter equals the product of the upper and lower left hand numbers, and the right hand letter equals the product of the upper and lower right hand numbers. The numerical value of the central letter equals the sum of the numerical values of the left and right hand letters.

Convert each letter to its numerical value, and read each pair of values as 2 digit numbers. In each row, the number in the centre equals the difference between the 2 digit values on the left and right.

The Carriage = 2, the Car = 3 and the Bus = 6

Split the left and right hand circles into 2 halves vertically. The numerical value of the letter in the upper left segment of the central circle equals the sum of the numbers in the left half of the left hand circle, and the letter in the lower left equals the sum of the numbers in the right half of the left hand circle. Repeat this pattern for the right hand circle.

In each row, multiply the numerical values of the left and right hand letters, putting the result in the centre.

In each diagram, convert each letter to its numerical value, and read the top and bottom pairs of letters as complete 2 digit values. Multiply these values together to give the 3 digit result written in the centre spaces.

In each row of the diagram, the numerical value of the middle letter equals the sum of the left and right hand numbers, subtracting 3.

In each column, add up each number and put the letter with this sum in the bottom circle.

In each row, the left hand number equals the total of the even valued letters in the middle box, and the right hand number equals the total of the odd valued letters in the middle box.

Split the left and right hand circles in half vertically. The letter with the numerical value of the sum of the digits in the left half of the left hand circle is placed in the top left segment of the central circle, and the letter with the numerical value of the sum of the digits in the right half of the left hand circle is placed in the top right segment of the central circle. Repeat this formula for the 2 halves of the right hand circle, putting the resulting letters in the lower segments of the central circle.

The Binoculars = 1, the Anchor = 3 and the Buoy = 5

Working in rows, add up the digits in each row and put the letter with this numerical value in the centre of the row.

In each circle, multiply the inverse alphabetical value of the upper left hand letter by the regular alphabetical value of the upper right hand letter to give the value in the lower segment.

Splitting the diagram in half both horizontally and vertically, each quarter contains a pattern of black squares, representing the letters W, X, Y and Z.

In each row, the left hand grid contains one line of black dots, the central one contains 2 lines and the right hand one contains 3 lines.
