Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression, there are no parentheses or exponents, so we'll perform multiplication and division first, and then addition and subtraction.

25 + 6 - 180 * 9 ÷ 20

First, perform the multiplication and division from left to right:

25 + 6 - (180 * 9 ÷ 20) 25 + 6 - (1620 ÷ 20) 25 + 6 - 81

Now, perform the addition and subtraction from left to right:

25 + 6 - 81 31 - 81

Finally, subtract 81 from 31:

31 - 81 = -50

So, the result of the expression is -50.
