-25-15-(-90):3x(-2)=-19+24-(-120):4x(-3)=-21+25+(-75):5x(-4)=​ ​

Penjelasan dengan langkah-langkah:

1. -25-15(-90):3×(-2)

=-25-15[(-90):3×(-2)]

=-25-15+[60]

=-40+60

=20

2. -19+24-(-120):4×(-3)

=-19+24+120:4×(-3)

=-19+24+[120:4×(-3)]

=-19+24+[-90]

=15-90

=-75

3. -21+25+(-75):5×(-4)

=-21+25+[(-75):5×(-4)]

=-21+25+[28]

=4+28

=32
