Answer 2

Let's solve the given mathematical expressions step by step:

1. 426 ⋅ 205 – 57,816 ÷ 72

First, let's perform the division: 57,816 ÷ 72 = 803

Now, we can substitute this value back into the expression: 426 ⋅ 205 – 803

Next, perform the multiplication: 426 ⋅ 205 = 87,330

Now, we can substitute this value back into the expression: 87,330 - 803

Finally, perform the subtraction: 87,330 - 803 = 86,527

Therefore, the value of the expression is 86,527.

2. (362,195 + 86,309) ÷ 56

First, let's perform the addition: 362,195 + 86,309 = 448,504

Now, we can substitute this value back into the expression: 448,504 ÷ 56

Perform the division: 448,504 ÷ 56 = 8,009

Therefore, the value of the expression is 8,009.

3. 2001 ÷ 69 + 58,884 ÷ 84

First, let's perform the divisions: 2001 ÷ 69 = 29 58,884 ÷ 84 = 701

Now, we can substitute these values back into the expression: 29 + 701

Perform the addition: 29 + 701 = 730

Therefore, the value of the expression is 730.

4. 42,275 ÷ (7005 – 6910)

First, let's perform the subtraction inside the parentheses: 7005 – 6910 = 95

Now, we can substitute this value back into the expression: 42,275 ÷ 95

Perform the division: 42,275 ÷ 95 = 445

Therefore, the value of the expression is 445.
