Answer 2

Let's solve each of these mathematical expressions step by step:

1. 401 • 2(543 + 177) First, perform the operations inside the parentheses: 543 + 177 = 720

Now, the expression becomes: 401 • 2(720)

Next, perform the multiplication: 401 * 2 = 802

Finally, multiply the result by 720: 802 * 720 = 577,440

So, 401 • 2(543 + 177) = 577,440.

2. 796 + 203 - 330 • 3 Perform the multiplication first: 330 * 3 = 990

Now, the expression becomes: 796 + 203 - 990

Now, perform the additions and subtraction: 796 + 203 = 999 999 - 990 = 9

So, 796 + 203 - 330 • 3 = 9.

3. 3 • 240 - 910 ÷ 5 Perform the division first: 910 ÷ 5 = 182

Now, the expression becomes: 3 • 240 - 182

Next, perform the multiplication: 3 * 240 = 720

Now, perform the subtraction: 720 - 182 = 538

So, 3 • 240 - 910 ÷ 5 = 538.

4. 916 ÷ 4 + (176 + 245) Perform the additions inside the parentheses first: 176 + 245 = 421

Now, the expression becomes: 916 ÷ 4 + 421

Perform the division: 916 ÷ 4 = 229

Now, perform the addition: 229 + 421 = 650

So, 916 ÷ 4 + (176 + 245) = 650.

5. 900 ÷ 5 - (618 - 518) Perform the subtraction inside the parentheses first: 618 - 518 = 100

Now, the expression becomes: 900 ÷ 5 - 100

Perform the division: 900 ÷ 5 = 180

Now, perform the subtraction: 180 - 100 = 80

So, 900 ÷ 5 - (618 - 518) = 80.

6. 903 ÷ 3 - 416 ÷ 4 Perform the divisions first: 903 ÷ 3 = 301 416 ÷ 4 = 104

Now, the expression becomes: 301 - 104

Perform the subtraction: 301 - 104 = 197

So, 903 ÷ 3 - 416 ÷ 4 = 197.

7. 715 ÷ 5 - (586 - 577) Perform the subtraction inside the parentheses first: 586 - 577 = 9

Now, the expression becomes: 715 ÷ 5 - 9

Perform the division: 715 ÷ 5 = 143

Now, perform the subtraction: 143 - 9 = 134

So, 715 ÷ 5 - (586 - 577) = 134.

8. 621 ÷ 3 + (900 - 586) Perform the subtraction inside the parentheses first: 900 - 586 = 314

Now, the expression becomes: 621 ÷ 3 + 314

Perform the division: 621 ÷ 3 = 207

Now, perform the addition: 207 + 314 = 521

So, 621 ÷ 3 + (900 - 586) = 521.

9. (747 + 156) ÷ 3 + 346 Perform the addition inside the parentheses first: 747 + 156 = 903

Now, the expression becomes: 903 ÷ 3 + 346

Perform the division: 903 ÷ 3 = 301

Now, perform the addition: 301 + 346 = 647

So, (747 + 156) ÷ 3 + 346 = 647.

10. 783 - 252 × 2 - 279 Perform the multiplication first: 252 × 2 = 504

Now, the expression becomes: 783 - 504 - 279

Perform the subtractions: 783 - 504 = 279 279 - 279 = 0

So, 783 - 252 × 2 - 279 = 0.
