Question

Calculează respectând ordinea efectuari operatiilor: a)15+3×(4×3-45÷9)-16=
b)25×(160-30×5)-8-(24+6:6)=

Answer 1

a) 15+3×(4×3-45:9)-16=
=15+3×(12-5)-16=
=15+3×7-16=
=15+21-16=
=36-16=20

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

Succes!

Answer 2

a) 15+3*(4*3-45:9)-16=
    15+3*(12-5)-16=
    15+3*7-16=
    15+21-16=
    15+5=20

b) 25*(160-30*5)-8-(24+6:6)=
    25*(160-150)-8-(24+1)=
    25*10-8-25=
    250-8-25=
    242-25=217
