Pedram Ghodrati Math Why do we have to learn algebra? Math is an academic subject which many students struggle to master. I remember when I was in high school‚ I always had a hard time understanding math. In senior year I almost dropped out of school because of the difficulty of high levels of math classes. I just read an article called‚ “Is Algebra Necessary?” by Andrew Hacker‚ an American political scientist and public intellectual. He is currently Professor Emeritus in the Department of Political

demanding when I became a high school student. It was quite a transition period as much as I can recall. Mathematics that was taught to us became more complex and was somehow much more difficult than what I was doing in primary school. High school math was presented as something straight forward. Our teachers during that time presented examples in class and gave the homework without further explanation. I knew I had to work hard and concentrate in order to get decent grades. The problems involved

1 2. Establish each of the following for all n ≥ 1 by the Principle of Mathematical Induction. Solution a) S(n): ==‚ S(1): = = =1‚ So S(1) is true. Assume S(k): = Consider S(k+1) = = +=-1+= -1. Hence‚ it follows that S(k)⇒S(k + 1) is true for all n ∈ Z+ by the Principle of Mathematical Induction. b) S( n) for n=1‚ = 2 = 2+(1-1). So S(1) is true. Inductive Step: assume S(k)is true‚ for some (particular) k ∈ Z+—that is‚ assume that =2+(k-1). For n=k+1‚ = + (k+1) = 2+ (k-1)+(k+1)=
