10. Ifodalarning qiymatini amallarning to‘g‘ri tartibiga rioya qilgan holda hisoblang: a) 2100 − (1856 + 1144) : 300 · 150; b) 49 000 : (3412 − 2712) : 10 + 3419.

a) Avval qavs ichidagi yig‘indini hisoblaymiz: \(1856+1144=3000\).

Keyin bo‘lish va ko‘paytirishni chapdan o‘ngga bajaramiz: \(3000:300\cdot150=10\cdot150=1500\).

Endi ayiramiz: \(2100-1500=600\).

b) Avval qavs ichidagi ayirmani hisoblaymiz: \(3412-2712=700\).

Bo‘lish amallarini chapdan o‘ngga bajaramiz: \(49000:700:10=70:10=7\).

So‘ng qo‘shamiz: \(7+3419=3426\).

Javob: a) 600; b) 3426.
