rumus=a+a=+ =a-a=+/- =a×a=+ =a÷a=+
=a+(-a)=+/- =a-(-a) =+/- =a×(-a)=- =a÷(-a)=-
=-a+(-a)=- =-a-(-a)=+/- =-a×(-a)=+ =-a÷(-a)=+
=-a+a=+/- =-a-a=- =-a×a=- =-a÷a=-
Penjelasan dengan langkah-langkah:
A. =38×(-26) -(-1.120)÷32+125
=(-988) -(-1.120)÷32+125
=(-988)-(-35)+125
=(-953)+125=(-828)
B.=138+(-38)×45÷(-15)- 258
=138+(-1.710)÷(-15)-258
=138+114-258
=252-258(-6)
C. =(-68)×35+624÷(-13)-(-732)
=(-2.380)+624÷(-13)-(-732)
=(-2.380)+48-(-732)
=(-2.332)-(-732)
=(-1.600)
