Weathered cement sidewalk displays math equation "2+S=4" written in blue chalk.
An outdoor daytime angled down close-up view of a weathered down gray colored cement sidewalk that has a math equation written on its surface in baby blue colored chalk. The math equation is positioned slightly diagonally at a left to right upward angle and reads "2+S=4". The "S" in the equation resembles a backwards "2". The gray colored cement sidewalk has small chips and dark colored markings spread throughout its surface. About two inches under the bottom left corner of the equation is a diagonal crack in cement that is slightly slanted from left to right at a downward angle. Towards the top left corner is a partial view of a patch of green grass that is to the left of the sidewalk.
