Calculation of Expression: 278002 - 520 * 708 / 390 + 407 * 320

To calculate the expression 278002 - 520 * 708 / 390 + 407 * 320, we need to follow the order of operations, which is commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

1. First, we perform the multiplication and division from left to right: - 520 * 708 = 368160 - 368160 / 390 = 944

2. Next, we substitute the results of the multiplication and division back into the original expression: - 278002 - 944 + 407 * 320

3. Then, we perform the remaining multiplication: - 407 * 320 = 130240

4. Finally, we perform the addition and subtraction from left to right: - 278002 - 944 + 130240 = 407298

So, the result of the expression 278002 - 520 * 708 / 390 + 407 * 320 is 407298.
