Answer 1

18:6+513-5х(91-84)=481
1)91-84=7
2)18:6=3
3)5×7=35
4)3+513=516
5)516-35=481

64:8+9:9-63:7=0
1)64:8=8
2)9:9=1
3)63:7=9
4)8+1=9
5)9-9=0

(6+2)×(701-698):(3×4:2)=4
1)6+2=8
2)701-698=3
3)3×4=12
4)12:2=6
5)8×3=24
6)24:6=4

4×8-8×(41-39)=16
1)41-39=2
2)4×8=32
3)8×2=16
4)32-16=16

Answer 2

Let's solve each expression step by step:

1. 18:6 + 513 - 5*(91-84) First, calculate the expression inside the parentheses: 91-84 = 7 Next, perform the multiplication: 5*(7) = 35 Finally, perform the addition and subtraction: 18/6 + 513 - 35 = 3 + 513 - 35 = 481.

2. 64:8 + 9:9 - 63:7 Perform the divisions first: 64/8 + 9/9 - 63/7 = 8 + 1 - 9 = 0.

3. (6+2) x (701-698) : (3x4:2) First, calculate the expression inside the parentheses: 6 + 2 = 8, 701 - 698 = 3 Next, perform the multiplication: 8 x 3 = 24 Then, perform the division: 3 x 4 / 2 = 6 Finally, perform the last multiplication: 24 / 6 = 4.

4. 4 x 8 - 8 x (41-39) Calculate the expression inside the parentheses: 41 - 39 = 2 Then, perform the multiplication: 8 x 2 = 16 Finally, perform the subtraction: 4 x 8 - 16 = 32 - 16 = 16.

So, the results of each expression are:

1. 18:6 + 513 - 5*(91-84) = 481
2. 64:8 + 9:9 - 63:7 = 0
3. (6+2) x (701-698) : (3x4:2) = 4
4. 4 x 8 - 8 x (41-39) = 16
