In each blank space write one of `+,-,xx,anddiv` signs so that the equation is true.
6 5 3 4 = 18

Options

A. `xx,xx,-`
B. `xx,-,xx`
C. `xx,+,xx`
D. `+,xx,div`

Answer

To solve the equation \( 6 \_\_ 5 \_\_ 3 \_\_ 4 = 18 \) by filling in the blanks with the operations +, -, ×, and ÷, we can follow these steps:

### Step 1: Identify the operations needed
We need to determine which combination of operations will yield the result of 18 when applied to the numbers 6, 5, 3, and 4.

### Step 2: Test different combinations
Let's start by testing the operations systematically.

1. **Try multiplication first**:
- If we multiply 6 and 5:
\[ 6 \times 5 = 30 \]
- Now we need to manipulate 30 with the remaining numbers (3 and 4) to reach 18.

2. **Next, consider subtraction**:
- We can subtract the product of 3 and 4 from 30:
\[ 3 \times 4 = 12 \]
- Now, we can subtract this from 30:
\[ 30 - 12 = 18 \]

### Step 3: Write the complete equation
Putting it all together, we have:
\[ 6 \times 5 - 3 \times 4 = 18 \]

### Step 4: Verify the solution
To ensure our solution is correct:
- Calculate \( 6 \times 5 = 30 \)
- Calculate \( 3 \times 4 = 12 \)
- Now, subtract: \( 30 - 12 = 18 \)

Since both sides of the equation are equal, our operations are correct.

### Final Answer:
The correct operations to fill the blanks are:
\[ 6 \times 5 - 3 \times 4 = 18 \]
