(c 2002+{[150-(26×15-95×3)×2]×3-24×5}=

Answer 1

a) 13 ×9-48:6+12 650: 11=
117-8+1 150=
109+1 150=
1 259


b) 32×17 +7 095:165-78:26=
544+43- 3=
587-3=
584


c) 2002+{[150-(26×15-95×3)×2]×3-24×5}=
2002+{[150-(390-285)×2]×3-120}=
2002+[(150-105×2)×3-120]=
2002+[(150-210)×3-120]=
2002+(- 60×3-120)=
2002+(- 180-120)=
2002-300=
