Question 1209539
.


In the post by @ElectricPavlov, the logic of the solution is correct.


The formulas that he uses for calculations are correct, too.


But all his output numbers, that are the results of his calculations, are WRONG.


His final answer is wrong, too.



It is because they systematically use inadequate calculator or inadequate calculation procedure 
for their calculations, which does not provide the necessary precision.



So, if you are looking to get a precise answer for your problems in Finance, 
which would be correct at the reference level of accuracy for your answer book, 
especially for annuity problems, then @ElectricPavlov is a bad source for such a goal.


As I look at their performance, I clearly see that they do not understand, at all,
what approximate calculations are and which requirements such calculations must satisfy.


So, their level of understanding approximate calculations corresponds to a 5th grade school student,
who makes such calculations for the first time in his life and who never took/got lessons 
from an experienced mentor on the subject.
