1. 3600 - 8000 : 50 + 30 ×(-45) =...............
2. 750 - 800 + 450 × (-8) : 150 =...........
3. 2800 : (-70) × 25 + 28 × 30 =......................
4. 300 × (-12) - 9000 : 15 + 4000 =...........
5. 200 + 2800 : (-40) - 300 ×(-6)

Answer 1

1. 3600 - 8000 : 50 + 30 x (-45)=
3600 - 160 + (-1350)=
3600 - 160 - 1350 = 2090
2. 750 - 800 + 450 x (-8) : 150=
-50 + (-3600) : 150=
-50 - 24 = - 74
3. 2800 : (-70) x 25 + 28 x 30=
-40 x 25 + 840 =
-1000 + 840 = -160
4. 300 x (-12) - 9000 : 15 + 4000=
-3600 -600 +4000= - 200
5.200 + 2800:(-40) - 300 x (-6)=
200 -70 +1800 =1930

Answer 2

1. 3600 - 8000 : 50 × (-45)
3600 - 160 - 1350
2090
2. 750 -800 + 450 × (-8) : 150
750 - 800 + (-3600 :150)
750 - 800 -24
= (-74)
3. 2800 : -70 ×25 +28 ×30
-196000×25+28×30
4900000+840
= 4900840
4. 300 × (-12) - 900 : 15 +4000
3600 - 600 +4000
=7000
5. 200+2800:(-40)-300x(-6)
200+(-70)+1800
=1930
*yg no 2 says kurang yakin wkwkwk
*perkalian sama pembagian dihitung duluan
