I suggest you can first watch Kirill Eremenko's teaching course in Udemy and when you finish basic courses go to youtube find Andy Briebel.

A good place to start is with the Tableau free online training at Tableau Training: View Training Courses
Tableau is and excel are fundamentally different  excel operates on an individual cell  you write a formula in a cell and then copy it to other cells 
Tableau is data base orient  using dimensions to categorize data and Measures which contain values  calculations are written using a combination of dimensions and measures  (think like writing your cell based formula in excel AND copying it along and entire column)  the Tableau calculation results in a new measure (or dimension) at a different level (aggregate level for example) in your data set
check out the training  start with some simple calculations and see the affect  then expand to more complex calculation  Calc I and Calc II in the training
Good luck
Jim

Raiyan k Aug 13, 2018 11:48 PM (in response to Jim Dehner)Hi Jim,
Thanks a lot for your detailed explanation.
What i do for now is i try to perform calculations in excel and try to write the same logic in Tableau.
However, I have gone through most of the recordings for Calculations but still struggling to write calculated logic for what i want to achieve.
Is there a way to learn step by step calculations and get logical aspects of understanding the calculations.
Thanks,
Raiyan.
