Question

m-am gandit la un numar.am adaugat la aceasta 2416 din suma am scazut 1987 la diferenta obtinuta am adaugat 1504 am scazut apoi,2938 si astfel am obtiunut rezultat 2016. La ce numar m-am gandit

Answer 1

[(a+2416)-1987]+1504-2938=2016
[(a+2416)-1987]+1504 =2016+2938
[(a+2416)-1987]+1504=5 004
(a+2416)-1987=5004-1504
(a+2416)-1987=3500
a+2416=3500+1987
a+2416=5487
a=5487-2416
a=3071

Answer 2

{[(a+2416)-1987]+1504}-2938=2016
{[(a+2416)-1987]+1504}=2016+2838
{[(a+2416)-1987]+1504}=4854
[(a+2416)-1987]=4854-1504
[(a+2416)-1987]=3350
(a+2416)=3350+1987
(a+2416)=5337
a=5337-2416
a=2921
Numarul la care m-am gandit era 2921!
