Question

1) Calculeaza:
94x47-(38x56-1252)=
214x25-(25x38-786)=
(2973:3+125x12)+324x5=
[(48600:100+512)-768:2]+17852=

2) Calculeaza respectand ordinea efectuarii operatiilor:
h) 180:9-16+21+144:8+225:3=
i) 13432+164x12-1395:15-1872:18
m)2+(3x4:6x50-50)+(50:10x6:3+20)=

Answer 1

1.4418-(2128-2125)=4418-3=4515
5350-(950-786)=5350-164=5186
(991+1500)+1620=2491+1620=4111
[(48600:100+512)-768:2]+17852=[(486+512)-384]+17852=[998-384]+17852=614+17852=18466.


2.h)180:9-16+21+144:8+225:3=20-16+21+18+75=4+39+75=43+75=118
i)13432+164×12-1395:15-1872:18=13432+1968-93-104=15400-93-104=15307-104=15302
m)2+(3×4:6×50-50)+(50:10×6:3+20)=2+(12:6×50-50)+(5×18+20)=2+(2×0)+(23+20)=2+0+43=2+43=45
