tolong dijawabb no 1-5 #pliss bsok dikumpulin

1. -150 - ( 12 x 10 ) : 3
= -150 - ( 120 : 3 )
= -150 - 40
= -190

2. ( 21 x 13 ) - 170 + ( -102 )
= 273 - 170 - 102
= 103 - 102
= 1

3. 1.250 + ( 24 x 115 ) - 1.100
= 1.250 + 2.760 - 1.100
= 4.010 - 1.100
= 2.910

4. 54 : ( 21 - 3 ) + 60 : ( -12 )
= ( 54 : 18 ) + ( -5 )
= 3 - 5
= -2

5. (3600:40)-(2200:11)+(3500:70)
= 90 - 200 + 50
= -110 + 50
= -60
