Question

a) 13x9-48:6+12650:11= b)32xx17+7095:165-78:26= C) 2002+{[150-(26x15-95x3)x2}x3-24x5}

Answer 1

13x9-48:6+12650:11=117-8+1150=109+1150=1259
32x17+7095:165-78:26=544+43-3=587-3=574
2002+{*150-(26x15-95x3)x2)*x3-24x5}
2002+{*150-(390-285)x2*x3-120}
2002+*(150-105x2)x3-120*
2002+*(150-210)x3-120*
2002+(-60x3-120)
2002+(-180-120)
2002+(-300)
1702

Answer 2

a) 13x9-48:6+12650:11=
= 117-8+1.150=
=1.259

b)32x17+7095:165-78:26=
=544+43-3=
=584

c) 2002+{[150-(26x15-95x3)x2]x3-24x5} =
=2002+{[150-(390-285)x2]x3-120} =
=2002+[(150-105x2)x3-120] =
=2002+[(150-210)x3-120] =
=2002+(-180-120) =
=2002+(-300) =1702
