tolong!!!!!!yakkkkk kak

1. 18 × (-25) + 625:5
= -(450) + 125
= -325

2. (3.589-1.508) × 4
= 2.081 × 4
= 8.324

3. 85 × 6 - 6.210 : (-10)
= 510 - (-621)
= 510 + 621
= 1.131

4. 12 × (-428) - 408 : 3
= -5.136 - 136
= -5.272

5. -(125:5) + 385 × 5
= (-35) + 1.925
= 1.890

6. -175×18 + 860:5
= (-3.150) + 172
= -2.978

1.
18 x (-25) + 625 : 5
= (18 x (-25)) + ( 625 : 5 )
= -450 + 125
= -325

2.
( 3589 - 1508 ) x 4
= 2.081 x 4
= 8.324

3. 448
4.−5.272
5. 1950
6. -2978
