13 x 11 - 2 x 9 x 18 + 11 = ?

Question

-141
-140
-187
-170

Answer 1

To solve the expression \( 13 \times 11 - 2 \times 9 \times 18 + 11 \), we will calculate it step by step:

1. First, calculate \( 13 \times 11 \): \[ 13 \times 11 = 143 \]

2. Next, calculate \( 2 \times 9 \times 18 \): \[ 2 \times 9 = 18 \] \[ 18 \times 18 = 324 \]

3. Now substitute these values back into the expression: \[ 143 - 324 + 11 \]

4. Perform the subtraction \( 143 - 324 \): \[ 143 - 324 = -181 \]

5. Now add 11: \[ -181 + 11 = -170 \]

So, the final result is: \[ \boxed{-170} \]
