The discussion centers on the calculation of the formula u = f k(k + 1)/n(n + 1) with specific values f = 700, k = 4, and n = 36. The user attempts to solve the equation but struggles with the division of 20 by 1332, mistakenly calculating it as 1332 divided by 20. The correct calculation yields approximately 0.015015015, which is crucial for obtaining the final result of u ≈ 10.51. The confusion highlights the importance of understanding the order of operations in mathematical calculations.

What does this have to do with long division or the rule of 78?Menomena said: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 the answer. I feel so dumb.
