Answer 1

№1
1) 11-2=9
2) 14/2=7
3) 18/9=2
4) 2*8=16
5) 9*7=63 
6) 63+16=79
№2
1)5*6=30
2) 30-12=18
3)7*7=49
4) 7*8=56
5) 49/49=1
6) 18/3=6
7)56-6=50
8) 50-1=49
№3
1) 6+3=9
2) 3*2=6
3)15-6=9
4)0*9=0
5) 4/4=1
6) 1*9=9
7) 0/8=0
8)0+9=9
9)9-0=9

Answer 2

18/(11-2)*8+9*(14/2)=16+63=79
7*8-(5*6-12)/3-49/(7*7)=56-18/3-49/49=56-6-1=49
0*(6+3)+4/4*(15-3*2)-0/8=9

Answer 3

Let's solve the given equations step by step:

1. 18:(11-2)8+9(14:2) First, perform the operations inside the parentheses: 18:(9)8+9(7) Next, perform the division: 28+97 Finally, perform the multiplication and addition: 16+63 = 79

2. 78-(56-12):3-49:(77) First, perform the operations inside the parentheses: 78-(30-12):3-49:(49) Next, perform the subtraction: 7*8-18:3-1 Then, perform the division: 56-6-1 Finally, perform the subtraction: 49

3. 0*(6+3)+4:4*(15-32)-0:8 First, perform the operations inside the parentheses: 0(9)+4:4*(15-6)-0:8 Next, perform the addition and multiplication: 0+4:4*(9)-0:8 Then, perform the division: 0+1*(9)-0:8 Finally, perform the division and subtraction: 0+9-0 = 9

So the solutions to the equations are:

1. 18:(11-2)8+9(14:2) = 79
2. 78-(56-12):3-49:(7*7) = 49
3. 0*(6+3)+4:4*(15-3*2)-0:8 = 9
