e)(567+68)x2-(940-385):5-259
f)30x3+6x[9+15x(6+6x9)]

Answer 1

567000-732:4=
567000-183=566817

144:6:2:6+18-16=
24:2:6+18-16=
12:6+18-16=
2+18-16=
20-16=
4

(892:4+149):6=
(223+149):6=
369:6=
61 rest 3

(567+68)x2-(940-385):5-259=
635x2-555:5-259=
1270-111-259=
1159-259=
900

30x3+6x[9+15x(6+6x9)]=
90+6x[9+15x(6+54)]=
90+6x[9+15x60]=
90+6x[9+900]=
90+6x909=
90+5454=
