To solve the expression \(9 + \frac{9}{9} + 9 \times 9 - 9\), follow the order of operations (PEMDAS/BODMAS):
- Parentheses/Brackets
- Exponents/Orders
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Apply these rules:
- Division: \( \frac{9}{9} = 1 \)
- Multiplication: \( 9 \times 9 = 81 \)
Now substitute these back into the expression:
\[ 9 + 1 + 81 - 9 \]
Addition and Subtraction from left to right:
\[ 9 + 1 = 10 \]
\[ 10 + 81 = 91 \]
\[ 91 - 9 = 82 \]
So, the result is 82.
