Question

No 1=8000:50-700 dikali (-9)-900=
no 2=-400 dikali -900:(-30)+1400=
no 3=3000+1500:(-50)-200 dikali (-7)=
no 4=25 dikali 90+4500:(-9)+(-16) dikali 60=

Answer 1

1. 8000 :50 -700 × (-9) -900
= 160 +6300 -900
= 5560
2. -400 × -900 :(-30) +1400
= 360000 : (-30) +1400
= 12000 +1400
= 13400
3. 3000 +1500:(-50) -200 × (-7)
= 3000 -30 +1400
= 4370
4. 25 × 90 +4500 :(-9) +(-16) ×60
= 2250 -500 -960
= 790
