Explicație pas cu pas:

33605-(215-m)=33190

(215-m)=33605+33190

(215-m)=66795

m=66795+215

m=67010

18089-(n+33)=17589

(n+33)=18089+17589

(n+33)=35678

n=35678-33

n=34645

10254+(3000-o)=10500

(3000-o)=10500-10254

(3000-o)=246

o=3000+246

o=3246

98000+(p-175)=99675

(p-175)=99675-98000

(p-175)=1675

p=1675+175

p=1850

Succes!
