i nkow that is just i dont know what to do with the negative number

4. ganeshie8

Ahh okay, negative number is just a number, no special treatment is required. \large\begin{align} \color{blue}{-2}(\color{green}{3}\color{red}{+}\color{purple}{6}) ~~&=~~ (\color{blue}{-2})(\color{green}{3})\color{red}{+} (\color{blue}{-2})(\color{purple}{6})\\~\\&=~~?\end{align}

5. CLOBBER02

i am so confused d

6. CLOBBER02

@ganeshie8

7. CLOBBER02

is it$-2(3+6)+?$

8. CLOBBER02

−2 x (3+6)+?

9. ganeshie8

\large\begin{align} \color{blue}{-2}(\color{green}{3}\color{red}{+}\color{purple}{6}) ~~&=~~ (\color{blue}{-2})(\color{green}{3})\color{red}{+} (\color{blue}{-2})(\color{purple}{6})\\~\\&=~~(-6) \color{Red}{+} (-12)\\~\\&=~~-6-12\end{align}

10. CLOBBER02

so its -6

11. ganeshie8

Yes! check this video when free https://www.khanacademy.org/math/pre-algebra/order-of-operations/ditributive_property/v/the-distributive-property

12. CLOBBER02

plz help with a few more

13. ganeshie8

first work the multiplication

14. ganeshie8

|dw:1433827301630:dw|

15. ganeshie8

remember how to multiply fractions ?

16. CLOBBER02

24/49

17. CLOBBER02

?

18. ganeshie8

nope, simply multiply numerators separately and denominators separately

19. CLOBBER02

i dont know how

20. ganeshie8

|dw:1433827601856:dw|

21. ganeshie8

before actually carrying out the multiplication, notice that we can cancel the common factor $$\large \color{red}{7}$$ : |dw:1433827704968:dw|

22. CLOBBER02

2/4

23. CLOBBER02

1/2

24. ganeshie8

how did u get 2/4 ?

25. CLOBBER02

i subed 4 and 8 and did the same on the top i did 1-3

26. ganeshie8

wow! im truely amazed! thats really clever xD

27. CLOBBER02

is it right?

28. ganeshie8

thats not right, but i really appreciate your bold attempt

29. CLOBBER02

thank u

30. ganeshie8

to add/subtract fractions, we need to have same denominator in the bottom

31. CLOBBER02

so how do u do that

32. ganeshie8

this is somewhat tricky but im sure it wont be that difficult for you, look at the bottom numbers, we have 4 and 8. they are not same, but we want them to be same... can you think of any tricks to "see" same number in the bottom ? |dw:1433828114996:dw|

33. CLOBBER02

wait i think i got it

34. CLOBBER02

1/8

35. ganeshie8

how ?

36. CLOBBER02

|dw:1433828313605:dw||dw:1433828377751:dw||dw:1433828408627:dw|

37. ganeshie8

Awesome! Looks you've mastered fractions!

38. ganeshie8

just wait, 2-3 is -1 right ?

39. CLOBBER02

no its just 1

40. ganeshie8

|dw:1433828521221:dw|

41. CLOBBER02

oooohhhhh

42. ganeshie8

2-3 is -1 ok

@ganeshie8

46. ganeshie8

look at the options in which option are they changing only the placement of parenthesis $$()$$ ?

47. CLOBBER02

b and c
