>>705824I got 16 too if you're looking at the actual yellow squares (4 along left and right side + all the individual tiny squares in the middle)
>>705826I count 40 if you're asking how many squares can you make using the lines
>16 individual 4x4 grid> 9 2x2's> 4 3x3's> 8 tiny squares> those tiny squares form another 2 ( the same size as the 16 squares)> plus the whole grid as 1 square
