Question

simplify.
$9^2 - 11 \times 4 + 2$
order of operations
( ) $x^2$ $\times \div$ $+ -$

Explanation:

Step1: Calculate the exponent

First, we calculate \(9^2\). By the definition of exponentiation, \(9^2 = 9\times9=81\).

Step2: Calculate the multiplication

Next, we calculate \(11\times4\). Using basic multiplication, \(11\times4 = 44\).

Step3: Perform the arithmetic operations

Now we substitute the results back into the original expression: \(81- 44+2\). First, do the subtraction: \(81 - 44=37\). Then, do the addition: \(37+2 = 39\).

Answer:

\(39\)
