1 answer

Let's simplify the expression step by step using the order of operations (PEMDAS/BODMAS):

The expression is:
\[ 3 \times 42 - 9 \times 2 \]

  1. Calculate the multiplications first:
    • \( 3 \times 42 = 126 \)
    • \( 9 \times 2 = 18 \)

Now we can rewrite the expression with these results: \[ 126 - 18 \]

  1. Now, perform the subtraction:
    • \( 126 - 18 = 108 \)

Thus, the simplified expression is: \[ 108 \]
