PEMDAS Pemdas! Don’t Stress

Let’s Work It! A decorative floor pattern has one red square tile surrounded by 12 blue tiles. Write and evaluate an expression to show how many total tiles (red and blue) are needed if there are 15 red tiles. Then make a table showing the total number of tiles if there are 15, 20, 25, or 30 red tiles
