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).

Here's how you can calculate it step by step:

1. First, perform the multiplications and divisions from left to right: 7 × 9 = 63 30 × 60 = 1800

2. Now, substitute the results back into the expression: 63 + 20 - 1800

3. Finally, perform the additions and subtractions from left to right: 63 + 20 = 83 83 - 1800 = -1717

So, 7×9+20-30×60 equals -1717.
