Rezolva urmatoarele exercitii :
8 x (2+5) =
(72:8)x(36:4) =
5x(6+3) =
72:8+9:2 =
27:3+64:8+72:9-25:5-18:2=
2x9+3x7-7x3+54:6=

Answer 1

1) 8×7=56 2)9×9=81 3)5×9=45 4)9+4,5=13,5 5)9+8+8-5-9=21 6)18+21-21+9=27

Answer 2

8x(2+5)=8x7=56
(72:8)x(36:4)=9x4=36
5x(6+3)=5x9=45
72:8+9:2=9+( noua impartit la 2 nu se poate ne da cu rest , probabil e o greseala )
27:3+64:8+72:9-25:5-18:2=9+8+8-5-9=17+8-5-9=25-5-9=20-9=11
2x9+3x7-7x3+54:6=18+21-21+9=39-21+9=18+9=27

Sper ca team ajutat ..daca vrei da-mi coroana
