My attempt at explaining to the irish getbigger
1. Using only logic I think this would be : M T W T M T W. Inverting the 'M' after each 'T'.
M T W T F S S is not a logical sequence, its just how a week is represented on a calendar.
2. In mathetical notation if you cross an equal sign it means 'not equal to'.
But the 'getbigger' answer is also correct IMO
3. you would use the bottom grid line as the base of a rectangle, so you would only need three lines to complete the rectangle.
