Question

1135:5+865:5-18 nhân 9 -18

Answer 1

\(1135:5+865:5-18\times9-18=227+173-162-18=\left(227+173\right)-\left(162+18\right)=400-180=220\)

Answer 2

\(1135:5+865:5-18\times9-18\)

\(=\left(1135:5\right)+\left(865:5\right)-\left(18\times9\right)-18\)

\(=227+173-162-18=400-162-18=238-18=220\)
