No, I can't see. What arrows? What numbers are the sum of what other two numbers? And where is the square?

You say "I mean red line , yellow line and black line are sum of two numbers also black rectangle is sum of three numbers and red rectangle is sum of four numbers" so
redLineSumOf2 = A(1,1) + A(1,4)
yellowLineSumOf2 = A(1,1) + A(1,3)
blackLineSumOf2 = A(1,1) + A(1,2)
blackRectSumOf3 = sum(A(1, 1:3))
redRectSumOf4 = sum(A(1, 1:4))
