Question 1182345
.


Regarding the long formulas in the post by @greenestamps,  I'd like to give couple advises to you.


First,  I am  100%  sure that for such calculations,  your teacher allows you to use a modern  Technology.


For such calculations,  I usually use  MS Excel  in my computer.


It is enough for you to copy the entire formula into the cell of the  MS Excel spreadsheet,  and you will get the number in one click.


Otherwise,  if you do not have  MS Excel or some equivalent software in your comp, 

you may use appropriate online calculators.


One such popular online calculator you may find at this web-site 

www.desmos.com


Again, you copy-paste the entire formula into the specialized window of this calculator and get the answer in one click.


This service is free of charge.


Surely,  the formulas that you copy-paste,  must be written  CORRECTLY - it is  YOUR  RESPONSIBILITY.


I think that to calculate so long formulas using the pocket calculator is 


            a)  a kind of torture, 

    and

            b)  an infinite source of errors.



In the  XXI  century nobody calculates this way.



Hope my advises will be useful for you.
