Question

Calculeaza:
25×(160-30×5)-8-(24+6÷6)=?
900-[(648÷4+350÷5)÷2]×3=?
95-[25÷(45÷9)+(36÷9×3-6)]+786÷6=?
{5+67÷[100-(60÷3-27÷3)-22]}×48=?

Answer 1

25×(160-30×5)-8-(24+6÷6)=
=25×(160-150)-8-(24+1)=
=25×10-8-25=
=250-8-25=
=242-25=
=217





900-[(648÷4+350÷5)÷2]×3=
=900-[(162+70):2]×3=
=900-(232:2)×3=
=900-116×3=
=900-348=
=552





95-[25÷(45÷9)+(36÷9×3-6)]+786÷6=
=95-[25:5+(4×3-6)]+131=
=95-[5+(12-6)]+131=
=95-(5+6)+131=
=95-11+131=
=84+131=
=215







{5+67÷[100-(60÷3-27÷3)-22]}×48=
={5+67:[100-(20-9)-22]}×48=
=[5+67:(100-11-22)]×48=
=[5+67:(89-22)]×48=
=(5+67:67)×48=
=(5+1)×48=
=6×48=
=288
