-20:4+(5×2)+15
14+(-2)+(10-2)+5
-14-2+10+(2+5)​

1.) -20 ÷ 4 + ( 5 × 2 ) + 15 =

= -5 ÷ 4 + ( 5 × 2 ) + 15

= -5 + 10 + 15

= 20

------------------------------------------

2.) 14 + (-2) + ( 10 - 2 ) + 5 =

= 14 - 2 + ( 10 - 2 ) + 5

= 14 - 2 + 8 + 5

= 25

-------------------------------------------

3.) -14 - 2 + 10 + ( 2 + 5 ) =

= -14 - 2 + 10 + 7

= 1

Kesimpulan :

• Hasil dari -20 ÷ 4 + ( 5 × 2 ) + 15 = 20
• Hasil dari 14 + (-2) + ( 10 - 2 ) + 5 = 25
• Hasil dari -14 - 2 + 10 + ( 2 + 5 ) = 1

Jawaban:

1. -5 + 10 + 15 = 20

2. 12 + 8 + 5 = 25

3. -16 + 10 + 7 = 1

maaf kalo salah
