Calculate 18 - 6 x 2

First, perform the multiplication:

$$18 - (6 \times 2) = 18 - 12$$

Then, perform the subtraction:

$$18 - 12 = 6$$

The value is $\boxed{6}$.

First, perform the division:

$$(12 \div 4) + 2 = 3 + 2$$

Then, perform the addition:

$$3 + 2 = 5$$

The value is $\boxed{5}$.

First, perform the division:

$$6 - (18 \div 3) = 6 - 6$$

Then, perform the subtraction:

$$6 - 6 = 0$$

The value is $\boxed{0}$.

First, perform multiplication and division from left to right:

$$(4 \times 5) + (8 \div 4) = 20 + 2$$

Then, perform the addition:

$$20 + 2 = 22$$

The value is $\boxed{22}$.

First, perform division and multiplication from left to right:

$$(16 \div 2) - (3 \times 2) = 8 - 6$$

Then, perform the subtraction:

$$8 - 6 = 2$$

The value is $\boxed{2}$.

First, perform multiplication and division from left to right:

$$(7 \times 3) + (27 \div 9) = 21 + 3$$

Then, perform the addition:

$$21 + 3 = 24$$

The value is $\boxed{24}$.

First, perform the operation inside the parentheses:

$$(8) + 3 \times 5$$

Next, perform the multiplication:

$$8 + (3 \times 5) = 8 + 15$$

Then, perform the addition:

$$8 + 15 = 23$$

The value is $\boxed{23}$.

First, perform the operation inside the parentheses:

$$5 + (6) \times 5$$

Next, perform the multiplication:

$$5 + (6 \times 5) = 5 + 30$$

Then, perform the addition:

$$5 + 30 = 35$$

The value is $\boxed{35}$.

First, perform the operation inside the parentheses:

$$4 \times 6 - (4)$$

Next, perform the multiplication:

$$(4 \times 6) - 4 = 24 - 4$$

Then, perform the subtraction:

$$24 - 4 = 20$$

The value is $\boxed{20}$.

First, perform multiplication and division from left to right:

$$(8 \times 3) - 17 + (15 \div 5) = 24 - 17 + 3$$

Next, perform addition and subtraction from left to right:

$$(24 - 17) + 3 = 7 + 3$$

Then, perform the addition:

$$7 + 3 = 10$$

The value is $\boxed{10}$.

First, perform division and multiplication from left to right:

$$(28 \div 4) + 2 - (2 \times 4) = 7 + 2 - 8$$

Next, perform addition and subtraction from left to right:

$$(7 + 2) - 8 = 9 - 8$$

Then, perform the subtraction:

$$9 - 8 = 1$$

The value is $\boxed{1}$.

First, perform multiplication and division from left to right:

$$(6 \times 2) - 2 - (40 \div 4) = 12 - 2 - 10$$

Next, perform addition and subtraction from left to right:

$$(12 - 2) - 10 = 10 - 10$$

Then, perform the subtraction:

$$10 - 10 = 0$$

The value is $\boxed{0}$.
