12. Pandalover485

i need help on two and three im not goodat thiss

13. Rag433

14. Rag433

So if you start with -4, what can you do to get to -8?

15. Pandalover485

im pretty sure its d

16. Pandalover485

i just wannaknow if im right

17. Rag433

Sorry, thats incorrect.

18. Pandalover485

aw really

19. Luis_Rivera

That type of multiple quetions i explain during private tutoring on my website. Contact me if you're interested

20. Rag433

Yeah, but lets stick with that for now. Why did you say D?

21. Rag433

@Pandalover485 why did you say D?

22. Pandalover485

becse the were add - 4 each time

23. Rag433

Okay, well does adding -4 work to get you from -8 to -16?

24. Pandalover485

no

25. Rag433

Right, so what single operation could you do to get from -8 to -16?

26. Pandalover485

-8

27. Rag433

that could work, but would that work to get you from -16 to -32?

28. Pandalover485

no?? becase 32 - 16 is 16

29. Rag433

Correct. Now all three of those numbers that you said (4, 8, 16) have a common factor... What is it?

30. Pandalover485

4...

31. Rag433

True, but we are not looking for the GCF here. Wouldn't 2 be a factor for those three numbers?

32. Pandalover485

4;1,4,2 8;1,8,2 16;1,16,8,2

33. Pandalover485

ya

34. Rag433

Okay, so if we have two as a factor. What can we do to the original number (-4) to make it equal -8 while still using 2?

35. Rag433

Hint: It's one of the four operations (add, subtract, multiply, divide)

36. Pandalover485

um........idk is it a

37. Rag433

No, it's not A either.

38. Rag433

Okay, multiply -4 by 2 and tell me what you get?

39. Rag433

@Pandalover485 don't give up now! Your so close to getting this!

40. Pandalover485

-6

41. Rag433

I have to go, here are thw answrs with explinations: 2. B: the rule of multiply 2 holds true for all numbers in the set 3. B: adding two every time gives you all numbers listed there.

42. Pandalover485

ok... thanks....
