Answer 1

Always use this order....

Parentheses

Multiply or Divide

Add or Subtract

1)  Add then Multiply  (Parentheses first)

2)  Multiply then Add

3)  Subtract then Multiply

4)  Multiply then Add inside the Parens then Add the two results

5)  Multiply then Divide (it doesn't matter in this case)

6)  Subtract in the Parens, Multiply, Multiply

Knowing these results, go ahead and do the rest of your homework yourself.

Answer 2

1.Addition in ()   (9 + 3] x 7

2. Multiply 98 - 5 X 7

3.  Subtract 5 X (9 - 1)

4. () first mult & add (15 * 3) + (4 + 5)

5. Mult. 5 * 4 ÷ 2

6. () first  subtract 6. 5(5 - 3) * 2

Evaluate each expression.

7. 2 x 9 + 5 * 3 = 18 + 15 = 33

8. (9 - 4) ÷ 5 = 5/5 = 1

9. 10 - 4 + 1 = 6+ 1 = 7

10. 15 - 18 ÷ 9 + 3 = 15 - 2 + 3 =16

11. 30 ÷ (12 - 6) + 4 = 30/6 + 4 = 5 + 4 = 9

12. (72 - 12) ÷ 2 = 60/2 = 30

13. 2(16 - 9) - (5 + 1) = 2(7) - 6 = 8

14. (43 - 23) - 2 * 5 = 20 - 10 = 10

15. 90 - 45 - 24 ÷ 2 = 90 - 45 - 12 = 45 - 12 = 33

16. 81 ÷ (13 - 4) = 81/9 = 9

17. 7 * 8 - 2 * 8 = 56 - 16 = 40

18. 71 + (34 - 34) = 71 + 0 = 71
