3. Calculează:
520 + 100 : 10 - 6 x 12 + 36:4 =
349 + 4 x 9 + 2 x 5 =
+ (
63: 7) + (14 x 2 x 6) - (9 x 8) =
(35:5) x (45:9) + ( 72:8):
(7 + 79) + (7 – 7) + (7:7) =
(24 :6 : 4) +
(7x 7) + (7
(4 x 11) + (4 x 22) – (6 X 8 - 21) + (145 +42:6) =
(84 – 8 x 8):5 + (3 x 6:2 + 17 x 5) =​

Răspuns:

Explicație pas cu pas:

280-21+0=259+0=259

349+36+10=385+10=395

520+100-72+9=620-72+9=548+9=557

7×5+9=35+9=44

(4÷4)+9+(28×6)-72=1+9+168-72=10+168-72=178-72=106

49+86+1+1=135+2=137

44+88-(48-21)+(145+7)=44+88-27+152=132-27+152=105+152=257

(84-64)÷5+(3×3+85)=20÷5+(9+85)=4+94=98
