`9 xx 9 div 3 + 9 xx 123 = ? - 19 - 23`

Options

A. 1176
B. 1174
C. 1177
D. 1175

Answer

To solve the expression \( 9 \times 9 \div 3 + 9 \times 123 = ? - 19 - 23 \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

### Step-by-step Solution:

1. **Identify the operations**: The expression consists of multiplication, division, addition, and subtraction.

2. **Perform the division first**:
\[ 9 \div 3 = 3 \]
So, we rewrite the expression:
\[ 9 \times 3 + 9 \times 123 = ? - 19 - 23 \]

**Hint**: Always perform division before multiplication when they appear together.

3. **Perform the multiplication**:
\[ 9 \times 3 = 27 \]
\[ 9 \times 123 = 1107 \]
Now, substitute these values back into the expression:
\[ 27 + 1107 = ? - 19 - 23 \]

**Hint**: Multiply the numbers after performing any division.

4. **Add the results**:
\[ 27 + 1107 = 1134 \]
Now, the equation looks like:
\[ 1134 = ? - 19 - 23 \]

**Hint**: Combine like terms before isolating the variable.

5. **Combine the constants on the right side**:
\[ -19 - 23 = -42 \]
So, we rewrite the equation:
\[ 1134 = ? - 42 \]

**Hint**: Always simplify the right side by combining constants.

6. **Isolate the variable \( ? \)**:
To find \( ? \), add 42 to both sides:
\[ ? = 1134 + 42 \]
\[ ? = 1176 \]

**Hint**: To isolate the variable, perform the inverse operation.

### Final Answer:
The value of \( ? \) is \( 1176 \).
