Which integer should be placed in the box such that the result is 2?
`[{(20-18-square) + 2} xx 4] divide 14`

Options

A. 3
B. 33
C. -3
D. 30

Explanation

To solve the problem, we need to find the integer that should be placed in the box so that the expression results in 2. The expression is given as:

\[ \left[ (20 - 18 - \text{box}) + 2 \right] \times 4 \div 14 = 2 \]

Let's break this down step by step.

### Step 1: Set up the equation
We start with the equation:

\[ \left[ (20 - 18 - \text{box}) + 2 \right] \times 4 \div 14 = 2 \]

### Step 2: Simplify the equation
First, we can multiply both sides by 14 to eliminate the division:

\[ \left[ (20 - 18 - \text{box}) + 2 \right] \times 4 = 2 \times 14 \]

This simplifies to:

\[ \left[ (20 - 18 - \text{box}) + 2 \right] \times 4 = 28 \]

### Step 3: Divide by 4
Next, we divide both sides by 4:

\[ (20 - 18 - \text{box}) + 2 = \frac{28}{4} \]

This simplifies to:

\[ (20 - 18 - \text{box}) + 2 = 7 \]

### Step 4: Isolate the box
Now, we can simplify the left side:

\[ (2 - \text{box}) + 2 = 7 \]

Combine like terms:

\[ 2 - \text{box} + 2 = 7 \]

This simplifies to:

\[ 4 - \text{box} = 7 \]

### Step 5: Solve for the box
Now, we isolate the box:

\[ -\text{box} = 7 - 4 \]

This gives us:

\[ -\text{box} = 3 \]

Multiplying both sides by -1:

\[ \text{box} = -3 \]

### Final Answer
The integer that should be placed in the box is:

\[ \text{box} = -3 \]
