The standard or normal magic square is defined as an arrangement of the first n² natural numbers (or positive integers) into a square matrix so that the sum of the numbers in each column, row and diagonal is the same magic number. This magic number is determined by n and is equal to n(n² + 1)/2.

Is there a trick to magic squares?

Solving a 3-by-3 Square

Given a little thought, I found that there is a simple calculation to find the “magic number” of any sized grid: Take the sum of every number on the board and divide it by the number of rows. In this case, the magic number is 1+2+… +9 = 45 / 3 = 15.

How do you solve a magic square puzzle?

To calculate the magic constant, add all nine numbers used in the magic square and divide by the number of rows. In our example, add 1+2+3+4+5+6+7+8+9 = 45, then divide by 3. The magic constant for this example is 15, as 45 / 3 = 15.

Is there only one solution to a magic square?

The sum is referred to as the magic constant. For a 3x3 magic square, there is actually only one normal solution and all of the puzzles are derived from rotations or reflections of that puzzle. The normal variations of these puzzles (the 3x3 puzzles that contain only 1-9) will have a magic constant of 15.

Where do I start magic square?

The placement is the same for any normal magic square with an odd number of columns or rows. Find the center square in the top row and write down the number 1 to get started. Example: If you have a 3 x 3 magic square, put 1 in the second box in the top row.
