Question

Calculează respectând ordinea operaţiilor.
206 x 3 + 4 x 129 =
900 + 343 x 4 =
1000 - (49 : 7 x 26) + (18 x 2- 60 : 10) =
209+ (900 - 224 x 2) - (176 x 3 - 29 x 8) =​

Answer 1

206×3+4×129=

618+516=1.134

900+343×4=900+1372=2.272

1000-(49:7×26)+(18×2-60:10)=

1000-(7×26)+(36-6)=

1000-182+30=

818+30=848

209+(900-224×2)-(176×3-29×8)=

209+(900-448)-(528-232)=

209+452-296=

661-296=365
