when the question was given to the class on Friday night, all I could think of was 180 subtract 162 to the remainder number and that could be the answer. The other method that I could thought of was that 360 is the degree of a whole circle what I have to do is subtract off 162x2 and that would be the answer.

But after discussion, I find that there are many ways that I can solve the equation. Through this activity, I was able to revise on what I had lost touch with for 6 years.
