Homework Statement u = f k(k + 1)/ n(n +1) f= 700, k =4, n=36 Homework Equations u = 700 x 4(4 + 1)/36(36 + 1) The Attempt at a Solution 700 x 20/1332 ≈ 10.51 I can't figure out how 20/1332 = 0.015015015, every time I divide it I get 0.0666, I literally have no clue how that is...

I know its subjective, but what is the definition of "mathematical maturity"?

I am curious as to where this book falls in the hierarchy of mathematical education. Could it be used effectively before a calculus course? Is calculus necessary before analysis?

Thank you both very much.
