The final answer is $39,087$.
Steps to Solve
-
Identify the order of operations According to the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), we first perform multiplication before addition and subtraction.
-
Perform the multiplication The multiplication in the expression is $97 \times 404$.
Calculating this gives:
$$ 97 \times 404 = 39,188 $$
- Substitute the multiplication result back into the expression Now, we have:
$$ 303 - 404 + 39,188 $$
- Perform the subtraction Now perform the subtraction:
$$ 303 - 404 = -101 $$
- Add the result of the subtraction to the multiplication result Now add $-101$ to $39,188$:
$$ -101 + 39,188 = 39,087 $$
The final answer is $39,087$.
More Information
The expression combines basic arithmetic operations: subtraction and multiplication. This type of question tests the ability to correctly apply the order of operations.
