'd' should be 3 or 8, but as it should be even, 'd' is 8.  'b' cannot be 0 (number ending with 02 cannot be divisible by 4) , 2 (cannot repeat) or 4 (number ending with 42 cannot be divisible by 4). it should be 1 or 3. cannot be 3 if so it exceeds 8000 which doesn't agree with 'd', so 'b' is 1.  Then solved for 'c'.3. If the vertical line splits top line to a:b and bottom line to c:d, should they satisfy a + c = b + d to areas to be equal? Idk, may be there is a better way to express it.------ Post added on [DATETIME="UT"]1722089827[/DATETIME]</blockquote>
