(284: 2 +68-39) xo =
6+(81:9 x 9 - 9) + 199 - 199x1 =
18 x 10 6 + (300-60):8+ 2387 =
(125 + 802) x2 - 108.2 =
(425x2 + 30882) 2+ 139=​

Răspuns :

Explicație pas cu pas:

(28:2+68-39)×0=0

6+(81:9×9-9)+199+199×1= 6+(9-9)+199+199×1=6+0+199+199×1=6+0+199+199=404

18×106+(300-60):8+2387= 18×106+240:8+2387=1908+30+2387=4325

(125+802)×2-1082=927×2-1082 = 1855-1082= 772

(425×2+30882):2+139 = (850+30882):2+139= 31732:2+139= 15886+139= 16005
