To complete the [tex]\(3 \times 3\)[/tex] magic square where the sum of the numbers in each row, column, and diagonal is 21, we need to determine the missing values. Here's a step-by-step solution:
1. Sum of each row, column, and diagonal:
The sum of numbers in any row, column, or diagonal is given to be 21.
2. First Row:
[tex]\[ 10 + 3 + \text{(unknown)} = 21 \\ 10 + 3 = 13 \rightarrow \text{unknown} = 21 - 13 = 8 \][/tex]
Hence, the first row is:
[tex]\[ 10 \quad 3 \quad 8 \][/tex]
3. Middle Column:
[tex]\[ 3 + 7 + \text{(unknown)} = 21 \\ 3 + 7 = 10 \rightarrow \text{unknown} = 21 - 10 = 11 \][/tex]
This means that the value in the third row, second column is 11.
4. Middle Row:
[tex]\[ \text{(unknown)} + 7 + \text{(unknown)} = 21 \][/tex]
We already know the value in the middle column:
[tex]\[ 10 + \text{(unknown)} = 21 \rightarrow \text{(unknown)} = 14 \rightarrow \text{middle left is 14 - 7} = 4 \][/tex]
This all clues us up to first middle row as [tex]\(4\)[/tex] and bot approaches [tex]\(10\)[/tex]:
[tex]\[ 4 \quad 7 \quad 10 \][/tex]
5. Bottom Row:
[tex]\[ \text{(unknown)} + 11 + \text{8} \][/tex]
Subtract known sums.
[tex]\[ Temp valued i.e.: \(22)=21-10 -> Next Unknown = 4 + then out) Mid: 14=when to 7 to sum, temp out10. \][/tex]
Thus the entries meaning:
