Answer 1

3000 + 1500 : -50 - 200 x - 7
= 3000 - 30 - 200 x - 7
= 2970 - 200 x - 7
= 2970 + 1400 = 4370
800 - 900 + 650 x -8 : 150
= -100 - 5200 : 150
= -100 - 34,6
= -134,6
1800 : -45 x 35 - 40 x 45
= -40 x 35 - 1800
= -1400 - 1800 = -3200
25 x 90 + 4500 : -9 + -16 x 60
= 2250 - 500 - 960
= 1750 - 960 = 790
