ME AJUDEM POR FAVOR
​

Answer 1

A)358-130+421= 228+421 = 649

B)533+321-629= 854-629 = 225

C)754-236+125-18 = 518+125-18 = 643-18 = 625

D)1060-(639+249)= 1060-888 = 172

E)936-(325+249) = 936-574 = 362

F)533-(21+62)+106= 533-83+106= 450+106 = 556

G)982-(514-325)+277= 982-189+277 = 793+277 = 1070
