I need you to produce a mathematical formula to convert the (x, y) coordinates to the corresponding point number. And the opposite.(as shown in the image).
For example, the coordinates ( 4 , 5 ) = point 55
Another example, the coordinates ( 8 , 7 ) = point 71
Note: coordinates will only be a whole numbers (No decimals).
