Answer 2

7. 1001+101×(200-188+9:9) = 1001+101×13 = 1001+1313 = 2314

9. 3892-(253+40:8)×2+42:7×9 = 3892-(253+5)×2+42:7×9 = 3892-258×2+42:7×9 = 3892-516+6×9 = 3892-516+54 = 3430

10. 4781-(407+63:9)×3+56:7:4 = 4781-(407+7)×3+56:7:4 = 4781-414×3+56:7:4 = 4781-1242+2 = 3541

11. 5×(42×17+9)-219+26×6 = 5×(714+9)-219+26×6 = 5×723-219+26×6 = 3615-219+156 = 3552

12. 3×(39×6)-313+31×3 = 3×234-313+31×3 = 702-313+93 = 482

Sper că te-am ajutat.
