“15% discount ” I believe you have seen this word at least once since you were born until now and I also believe it gives you at least a bit of the glue what I’ve been working and studying on in math class. I can say that I know nothing about Percentage except the sign that represents a percentage “%”. It has been a really good lesson to take during my math class. We did a lot of exercises related to the percentage. I also meet a lot of struggles during the lesson, but I always find a way to solve it as fast as possible because I want to make sure I know exactly what I was doing. Khan plays a really important role in my life because when I have free time I always try to do at least 3-4 Khan Assignment that Sam (our math’s facilitator) assigned to us. At the end of this round, I finally know at least 95% of the percentage lesson.
