Tolong dibantu ya, pake cara

Jawaban:

1. 10 X (-8) + 7

= -80 + 7

= -73

2. 450 – (-250) + 100 – 25

= 450 + 250 + 100 – 25

= 800 – 25

= 775

3. -25 + (98 – (-10) ) – 112

= -25 + 108 – 112

= 83 – 112

= -29

4. ( 4 + (-24) ) X ( 10 – (-5) )

= -20 X 15

= -300

5. 13 X ( 140 : (-7) ) + (-2) X 15

= 13 X -20 + (-2) X 15

= -260 + -30

= – 290

Jawaban:

1. –73

2. 775

3. –29

4. –300

5. –290

6. 1.039

7. 1.040

8. 1.710

Penjelasan dengan langkah-langkah:

1. 10 × (-8) + 7 = -80 + 7 = -73

2. 450 – (-250) + 100 – 25 = 700 + 100 – 25 = 800 – 25 = 775

3. -25 + (98 – (-10)) – 112 = -25 + 108 – 112 = 83 – 112 = -29

4. (4 + (-24)) × (10 – (-5)) = -20 × 15 = -300

5. 13 × (140 : (-7)) + (-2) × 15 = 13 × (-20) + (-2) × 15 = -260 + (-30) = -290

6. 412 : 4 + 104 × 9 = 103 + 936 = 1.039

7. 1.125 – 125 + 1.000 : 25 = 1.125 – 125 + 40 = 1.000 + 40 = 1.040

8. 60 × 32 – 95 – 115 = 1.920 – 95 – 115 = 1.825 – 115 = 1.710
