How do we solve the problem below?
Should we solve the problem from the right to the left? Or left to right? Or we will multiply first?
To avoid these confusions – we teach students the powerful “spell” – PEMDAS – to help them remember the order of Math operations.
PEMDAS is a useful tip that helps children get used to the calculation process instead of just paying attention to finding answers. This approach is shown in Singapore Math. At Everest, Singapore Math “focuses on mathematical problem solving and emphasizes conceptual understanding, skills proficiency, learning of process skills, metacognition and the development of a positive attitude towards mathematics”.
