= -27500 + 700
= -26800
2. -4500 ÷ (-30) + 8 × (-300) - 1500 = 150 + (-2400) - 1500
= -2250 - 1500
= 3750
3. 600 +80 × (-9) + 1800 ÷ 25 = 600 + (-720) + 72
= -120 + 72
= -48
4. 2400 - 6000 ÷ 20 + 40 × (-75) = 2400 - 300 + (-3000)
= 2100 + (-3000)
= -900
5. 8000 ÷ 50 - 70 × (-9) -90 = 160 + 630 -90
= 790 - 90
= 700
semoga membantu...
maaf kalo salah...
500 * (-18) = -9000
-500 - (-9000) = 8500 + 700= 9200
2. -4500:(-30) = 150
8 * (-300) = -2400
150 + (-2400) = -2250 + 700 = -1550
3. 80 * (-9) = -720
1800 : 25 = 72
600 + (-720) + 72 = - 48
4. -6000 : 20 = -300
40 * (-75) = - 3000
2400-300+(-3000) = - 900
5. 8000:50 = 160
700 * (-9) = -6300
160 - (-6300) - 900 = 5590
maaf jika jawaban saya ada yang keliru...
