## Is there a mathematical way to solve Sudoku?

In fact, mathematical thinking in the form of logical deduction is very useful in solving Sudokus. The most basic strategy to solve a Sudoku puzzle is to first write down, in each empty cell, all possible entries that will not contradict the One Rule with respect to the given cells.

## Is there a formula for magic square?

Remember the equation: 54 (the target number) minus 34 (our original magic square total) = 20. And then you divide 20 by 4 to get 5 with no remainder! All you have to do is add 5 to each of the 16 numbers in your new grid and it will work.

## Why is it called a magic square?
