2. -85 : 17 =
3. -284 : (-71) =
4. 23 × 7 + 23 × (-6) =
5. -3 × (-20) + (-6) × (-20) =​

1. -43 × (-16) =

1.) -43 × (-16)

= distribusikan menjadi = 43 × 16 = 688

maka hasil benarnya = -688

2.) -85 ÷ 17

= distribusikan menjadi = 85 ÷ 17 = 5

maka hasil benarnya = -5

3.) -284 ÷ (-71)

= distribusikan menjadi = 284 ÷ 71 = 4

maka hasil benarnya = -4

4.) 23 × 7 + 23 × (-6)

= distribusikan menjadi = 23 × 7 + (23 × -6)

= 161 + (23 × -6)

= 161 + (-138)

= 23

maka hasil benarnya = 23

5.) -3 × (-20) + (-6) × (-20) =

= (-3 × (-20)) + (-6) × (-20))

= 60 + 120

= 180

Jawaban:

1. -43 × (-16) = 688

2. -85 : 17 = 5

3. -284 : (-71) = 4

4. 23 × 7 + 23 × (-6)

= (23 × 7) + (23 × (-6))

= 161 + (-138)

= 23

5. -3 × (-20) + (-6) × (-20)

= (-3 × (-20)) + ((-6) × (-20))

= 60 + 120

= 180
