Explanation:

What is the order of operations?

The order of operations is a sequence in which operations should be performed to evaluate a mathematical expression correctly. A common way to remember is PEMDAS:

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

To simplify the expression 19×33−2(16+23) using the order of operations, first solve the operations inside the parentheses:

• 16 + 23 = 39

Now we multiply:

• 2 × 39 = 78

The expression now looks like this:

• 19 × 33 − 78.

Perform the multiplication before the subtraction:

• 19 × 33 = 627

Now that we have done the multiplication, we can subtract:

• 627 - 78 = 549

Therefore, the expression simplified is 549.
