Question

Va rog ajutatima dar sa numi scrieti decat rezultatul sami scrieti rezolvarea si dau coronita.
1) [ 847 - ( 1 000 - 54 x 18 ) : 4 ] : 10 + 16 =
2) 5 550 - [ 100 + 100 x ( 100 - 8 x 9 ) - 2 x 19 x 10 ] x 2 =
3) [ ( 945 : 5+ 175 : 7 ) x 2 ] : ( 200 - 98 x 2 ) =

Answer 1

1) [847 - (1000-54x18):4]:10+16=
[847-(1000-972):4]:10+16=
(847-28:4):10+16=
(847-7):10+16=
840:10+16=
84+16=100

2) 5550-[100+100x(100-8x9)-2x19x10]x2=
5550-[100+100x(100-72)-2x19x10]x2=
(100+100x18-2x19x10)x2=
(100+1800-380)x2=
(1900-380)x2=
1520x2= 3040

3) [(945:5+175:7)x2]:(200-98x2)=
[(189+25)x2]:(200-196)=
(214x2):4=
428:4= 107
