Penyelesaian :
Sifat - sifat Penjumlahan :
( - ) + ( - ) = ( - )
( + ) + ( - ) = ( + )
( - ) + ( + ) = ( + )
Sifat - sifat Pengurangan :
( - ) - ( - ) = ( - )
( + ) - ( - ) = ( + )
( - ) - ( + ) = ( - )
Sifat - sifat Perkalian :
( - ) × ( - ) = ( + )
( - ) × ( + ) = ( - )
( + ) × ( - ) = ( - )
Sifat - sifat Pembagian :
( - ) ÷ ( - ) = ( + )
( - ) ÷ ( + ) = ( - )
( + ) ÷ ( - ) = ( - )
Jawaban 1.
-3 + 6 × (-2)
= -3 + 6 × (-2)
= -3 + (6 × (-2))

4 + 8 : (-2) × 7
= 4 + 8 : (-2) × 7
= 4 + (8 : (-2)) × 7
= 4 + (-4) × 7
= 4 + -28
= -24
Jawaban 3.
-16 - 20 × (-3)
= -16 - 20 × (-3)
