Every Row, Column, and Long Diagonal Adds to the Same Total: Complete the Magic Square Using the Numbers Provided
A magic square is a square grid filled with distinct positive integers in the range from 1 to n^2, where n is the number of rows (or columns) in the grid. The magic square has the property that the sum of the numbers in each row, column, and diagonal is the same. This unique property makes magic squares a fascinating topic in mathematics, with a rich history and numerous applications.
In this article, we will explore a magic square with a twist. We will be given a partially filled magic square and will need to complete it using the numbers provided. The magic square is shown below:
| 14 | a | 7 |
|---|---|---|
| 4 | 9 | 2 |
| 3 | 8 | b |
Every row, column, and long diagonal in this magic square must add up to the same total. Our task is to find the values of 'a' and 'b' that complete the magic square.
The Magic Square Property
A Fundamental Concept in Mathematics
The magic square property is a fundamental concept in mathematics that has been studied for centuries. It is a unique property that makes magic squares a fascinating topic in mathematics. The property states that the sum of the numbers in each row, column, and diagonal is the same.
Mathematically, this can be represented as:
- Row sum = Column sum = Diagonal sum
For example, in the magic square above, the row sum of the first row is 14 + a + 7. The column sum of the first column is 14 + 4 + 3. The diagonal sum of the long diagonal is 14 + 9 + 2. All these sums must be equal.
Finding the Values of 'a' and 'b'
A Mathematical Puzzle
To find the values of 'a' and 'b', we need to use the magic square property. We can start by finding the row sum of the first row, which is 14 + a + 7. We can also find the column sum of the first column, which is 14 + 4 + 3. Since the row sum and column sum must be equal, we can set up an equation:
14 + a + 7 = 14 + 4 + 3
Simplifying the equation, we get:
a + 21 = 21
Subtracting 21 from both sides, we get:
a = 0
However, this is not possible since 'a' is a positive integer. Therefore, we need to re-examine our equation.

A Closer Look at the Magic Square Property
Let's take a closer look at the magic square property. We can see that the row sum of the first row is 14 + a + 7. The column sum of the first column is 14 + 4 + 3. The diagonal sum of the long diagonal is 14 + 9 + 2. All these sums must be equal.
We can also see that the row sum of the second row is 4 + 9 + 2. The column sum of the second column is 4 + 8 + b. The diagonal sum of the long diagonal is 14 + 9 + 2. All these sums must be equal.
Setting Up a System of Equations
A Mathematical Approach
We can set up a system of equations using the magic square property. We can start by setting up an equation for the row sum of the first row:
14 + a + 7 = 21
We can also set up an equation for the column sum of the first column:
14 + 4 + 3 = 21
We can also set up an equation for the diagonal sum of the long diagonal:
14 + 9 + 2 = 25
However, we can see that the diagonal sum is not equal to the row sum or column sum. Therefore, we need to re-examine our equations.
