Answer 2

Answer:

(a)100-[20+{40-(30-20)}]

Step-by-step explanation:

=100-[20+{40-10}]

=100-[20+{40+10}]

=100-[20+50]

=100-70

=30

(B)90-[90-{45+(45÷15)]

=90-[90-{45+3}]

=90-[90-48]

=90-42

=48

(C)60-[48-{16+(8-4)}]

=60-[48-{16+4}]

=60-[48-20]

=60-28

=32

(D)836-[665-{165-(264÷66)}]

=836-[665-{165+4}]

=836-[665-2,169]

=836-1,504

=-668

(E){(31-9+8)÷10}×15+5

={30÷10}×15+5

=3×15+5

=45+5

=50

(F)[(2÷1×2+1-1)-(10÷5-1x3+2)]

=[(4)-(1)]

=[4-1]

=5
