Okay, so let's solve the first one together. What do you think the first one is based on its context?

6. anonymous

a

7. anonymous

What property states that any number multiplied by 0 is always 0?

8. anonymous

d

9. anonymous

So which number does that go along with?

10. anonymous

1

11. anonymous

Correct. Now number two says that 1/16 x 16/1 = 1. Which letter would that be?

12. anonymous

1d 2? 3? 4?

13. anonymous

c

14. anonymous

I would have to disagree with ya' on that one. Which property states that the opposite of a number multiplied by itself is 1?

15. anonymous

e

16. anonymous

We're not really dividing here, and it doesn't have a -1 in it. Which other one could it be?

17. anonymous

b

18. anonymous

Okay, it would be letter A and here's why: Reciprocal means that the opposite of a number multiplied by itself if 1. I'll show you the example: $\frac{ 1 }{ 16 } * \frac{ 16 }{ 1 } = \frac{ 16 }{ 16 } = 1$

ok 1d 2a

20. anonymous

3? 4?

21. anonymous

Before I go further, are you understanding this or just looking for the answers?

22. anonymous

im understanding it i alreday had the frist one correct

23. anonymous

Okay, so number 3 would be the one that multiplied by -1 is either a double negative or the opposite of the number. Which property is that one?

24. anonymous

a

25. anonymous

right?

26. anonymous

You're already stated that a is an answer. Which property states something about "-1"? Key word: -1

27. anonymous

You've*

28. anonymous

you can use it more then one time

29. anonymous

Even if you can, that's not the correct answer. Which property states about multiplying with negative one?

30. anonymous

oh d

31. anonymous

That states that any number multiplied by 0 = 0. 18 * (-1) = -18 Which property states about multiplying negative numbers?

32. anonymous

ok?

33. anonymous

e

34. anonymous

You're almost there, but that's division. We're doing multiplication.

35. anonymous

dang it

36. anonymous

Which one states about multiplying negative numbers?

37. anonymous

C!!!!!!

38. anonymous

Correct! Now I've noticed that number 4 is left out. What does number 4 state?

39. anonymous

5 ÷ (–1) = –5 e
