PEMDAS & SADMEP: Senior Oliver Yang and Math Teacher Sean Lieblang pose together for a photo with stuffed animals. Lieblang’s stuffed animals, Pemdas and Sadmep, are two very important aspects of the Chapter 1 curriculum in Algebra 2/Trigonometry. These characters help ensure that the students remember the importance of simple algebra strategies. “Back in my sophomore year, Mr. Lieblang taught us about simplifying expressions and solving equations.” Yang said. “Whenever he spoke of PEMDAS and SADMEP specifically, I always thought about his two stuffed animals.”
