Equal sums task
Square matrix is a matrix with the same number of rows and columns. Square matrices of variable dimensions are displayed on the screen.
Matrix elements should be set so that the sum of the elements within each row and column of the matrix is equal.
There are 2 variants (paradigms) of this task.
In the first variant, the missing values should be entered on the main diagonal of the square matrix (there are infinitely many solutions).
In the second variant, the elements of the square matrix should be moved using the "drag and drop" action.
