Answer 3

To solve the expression (((9+9*9)*10)-60)/90, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here's the step-by-step solution:

1. Start by evaluating the multiplication inside the inner parentheses: 9 * 9 = 81.
2. Replace the inner parentheses with the result: ((9+81)*10-60)/90.
3. Next, perform the addition inside the remaining parentheses: 9 + 81 = 90.
4. Replace the remaining parentheses with the result: (90*10-60)/90.
5. Perform the multiplication: 90 * 10 = 900.
6. Replace the multiplication with the result: (900-60)/90.
7. Perform the subtraction: 900 - 60 = 840.
8. Replace the subtraction with the result: 840/90.
9. Finally, perform the division: 840 / 90 = 9.

Therefore, the value of the expression (((9+9*9)*10)-60)/90 is 9.
