Tolong doak yang baik

1. = 500 x ( -18 ) – 8.000 : 16 + 700
= [ ( 500 x ( -18 ) ] – ( 8.000 : 16 ) + 700
= -9.000 – 500 + 700
= -9.000+( -500 ) + 700
= -9.500 + 700
= -8800

2. = -4.500 : ( -30 ) + 8 x ( -300 ) – 1.500
= [ ( -4.500 ) : ( -30 ) ] + [ 8 x ( -300 ) ] – 1.500
= 150 + ( -2400 ) – 1.500
= 2.250 – 1.500
= 750

3. = 600 + 80 x ( -9 ) + 1.800 : 25
= 600 + [ 80 x ( -9 ) ] + ( 1.800 : 25 )
= 600 + ( -72 ) + 72
= 528 + 72
= 600

4. = 2.400 – 6.000 : 20 + 40 x ( -75 )
= 2.400 – [ 6.000 : 20 ] + [ 40 x ( -75 )]
= 2.400 – 300 + ( – 3.000 )
= 2.100 + ( – 3.000 )
= – 900

5. = 8.000 : 50 – 700 x ( -9 ) – 900
= ( 8.000 : 50 ) – [ 700 x ( -9 ) ] – 900
= 160 – ( – 6300 ) – 900
= 160 + 6300 – 900
= 6460 – 900
= 5560

6. = -400 x 16 – 900 : ( -30 ) + 1.400
= ( -400 x 16 ) – [ 900 : ( -30 ) ] + 1.400
= -6.400 – ( -30 ) + 1.400
= -6.400 + 30 + 1.400
= -6.100 + 1.400
= 4.700
