Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right):

Given expression: 27 + 312 ÷ 48 + (900 – 669) - (8 - 25) - 1 + 809 ÷ 9

1. Solve inside the parentheses/brackets:

   • Inside the first set of parentheses: 900 - 669 = 231
   • Inside the second set of parentheses: 8 - 25 = -17

2. Continue solving from left to right: 27 + 312 ÷ 48 + 231 - (-17) - 1 + 809 ÷ 9

3. Perform the multiplications and divisions: 312 ÷ 48 = 6.5 (approximately) 809 ÷ 9 = 89.888... (approximately)

4. Substitute the results back into the expression: 27 + 6.5 + 231 + 17 - 1 + 89.888...

5. Add the numbers together: 27 + 6.5 + 231 + 17 - 1 + 89.888... ≈ 372.388...

So, the result of the expression is approximately 372.388...
