Answer 2

Calculation of Expressions

Let's calculate the values of the given expressions step by step:

1. 16 + 350 ÷ 7 - 21: - First, divide 350 by 7, which equals 50. - Then, add 16 and 50, which equals 66. - Finally, subtract 21 from 66, which equals 45.

2. 72 ÷ (17 - 8) + 5: - First, subtract 8 from 17, which equals 9. - Then, divide 72 by 9, which equals 8. - Finally, add 8 and 5, which equals 13.

3. 49 ÷ 7 + 18 - 9: - First, divide 49 by 7, which equals 7. - Then, add 7 and 18, which equals 25. - Finally, subtract 9 from 25, which equals 16.

4. 98 - 6 × 4 + 17: - First, multiply 6 by 4, which equals 24. - Then, subtract 24 from 98, which equals 74. - Finally, add 74 and 17, which equals 91.

5. 630 ÷ 7 + 40 ÷ (4 × 2) + 6 × 4 ÷ (560 ÷ 70) × 5: - First, divide 630 by 7, which equals 90. - Then, multiply 4 by 2, which equals 8. - Next, divide 40 by 8, which equals 5. - After that, divide 560 by 70, which equals 8. - Then, multiply 6 by 4, which equals 24. - Finally, multiply 24 by 5 and divide the result by 8, which equals 15. - Now, add 90, 5, and 15, which equals 110.

Therefore, the values of the given expressions are as follows: - 16 + 350 ÷ 7 - 21 = 45 - 72 ÷ (17 - 8) + 5 = 13 - 49 ÷ 7 + 18 - 9 = 16 - 98 - 6 × 4 + 17 = 91 - 630 ÷ 7 + 40 ÷ (4 × 2) + 6 × 4 ÷ (560 ÷ 70) × 5 = 110
