7÷7+7×7-7÷7+7-7×7-7;

Answer 1

(24:3×6+9×4:3+15×2):10+9:9=

=(48+12+30):10+1

=90:10+1

=9+1

=10

(100-28):9×(12:6+5)=

=72:9×(2+5)

=72:9×7

=56

(15+5×5):10×(7×5-30:6)=

=(15+25):10×(35-5)

=40:10×30

=120

7:7+7×7-7:7+7-7×7-7=

=1+7×7-1+7-7×7-7

=0+0+0

=0

Answer 2

(24:3×6+9×4:3+15×2):10+9:9=
