Jawaban:

1. 118

2. -249

3. 1562

4. -72

Penjelasan dengan langkah-langkah:

1. 7 × ( 10+8 ) – 8 =

= 7 × 18 – 8

= 126 – 8

= 118

2. ( 19 – 66) – 202 =

= -47 – 202

= -249

3. ( 1576 – 9 – 2) + 18 : (-6) =

= ( 1567 – 2 ) + 18 ÷ (-6)

= 1565 + 18 ÷ (-6)

= 1565 + (-3)

= 1562

4. ( (20+5) : 5- 68) – 9=

= ( 25 ÷ 5 – 68 ) – 9

= ( 5 – 68 ) – 9

= -63 – 9

= -72
