Answer 1

9) 1000-(28:4×25)+(19×3-39)=
1000-(7×25)+(57-39)=
1000-175+18=
825+18=843.

[4×(5×12-6×5)-5×4]:10-2×(12×3-9×4)=
[4×(60-30)-20]:10-2×(36-36)=
(4×30-20):10-2×0=
(120-20):10-0=
100:10-0=10

Answer 2

1000-(28:4×25)+(19×3-39)=
1000-(7×25)+(57-39)=
1000-175+18=843;
[4×(5×12-6×5)-5×4]:10-2×(12×3-9×4)=
[4×(60-30)-5×4]:10-2×(36-36)= .
(4×30-5×4):10-2×0=
(120-20):10-2×0=
100:10-2×0=10-0=10.
