Javob va yechimni ko‘rish
Javob: 45
Ifodani birinchi qavs ichidan boshlaymiz.
$156:2=78$, shuning uchun $156:2-18=78-18=60$.
Keyin $ (78-18):2 = 60:2 =30$.
Endi ikkinchi qavsga o'tamiz: $18:6=3$, demak $18:6+2=3+2=5$.
Uchinchi qism $3\cdot(18:6+2)=3\cdot5=15$.
Oxirgi natija $30+15=45$, ya’ni javob **B) 45**.
