Answer 2

To solve the expression 789:390 + (143 * 69) - 100, 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 this case, you should first perform the operations inside the parentheses and then follow the order of operations.

Here's the step-by-step calculation:

1. Calculate the expression inside the parentheses: 143 * 69 = 9852

2. Now, the expression becomes: 789:390 + 9852 - 100

3. Perform division: 789 divided by 390 is approximately 2.0231 (rounded to four decimal places).

4. Now, the expression becomes: 2.0231 + 9852 - 100

5. Finally, perform addition and subtraction from left to right:

   2.0231 + 9852 = 9854.0231

   9854.0231 - 100 ≈ 9754.0231 (rounded to four decimal places)

So, the result of the expression 789:390 + (143 * 69) - 100 is approximately 9754.0231.
