Imagine a square that contains a perfect 4x4 grid. Now, imagine a square that same size as the ones in the grid placed in the vertical center of the grid, halved horizontally by the first horizontal line from the top inside the large square. Add another one of these squares halved horizontally by the first horizontal line from the bottom inside the large square. How many total squares are in this image? You may count overlapping squares. You may find the correct answer by counting each square individually, or by using a mathematical formula.
