Answer 2

Let's solve these expressions step by step:

1. (395 * 52 - 603) * 25 - 960 : 24 First, perform the operations inside the parentheses: (395 * 52 - 603) = 20535 Then, multiply the result by 25: 20535 * 25 = 513375 Finally, divide the result by 24: 513375 / 24 = 21390.625

So, (395 * 52 - 603) * 25 - 960 : 24 = 21390.625

2. (320 * 8 - 30) : 2 First, perform the operations inside the parentheses: (320 * 8 - 30) = 2540 Then, divide the result by 2: 2540 / 2 = 1270

So, (320 * 8 - 30) : 2 = 1270

Please note that both of these calculations involve decimal points, so the final answers are real numbers.
