Group members: Teng Jun and Wesley b) -23 is more than -27, not -23 is less than -27. Also, a note, the -27 has no '-' sign. c) (-12)power of 2 is less than -200, not more than -200

For the third piece of work, example 2 part D the question is 4-(-9)-5 the working is since there are two negatives it means that 4 is suppose to be added to 9 therefore the answer for 4-(-9) is 13 then minus 5 as stated in the operation finally the answer is 8.

Group members: Joel Tan and Timothy Luk. We found out that part a, b, c, d is correct. as 13 is more than -13, -23 is less than 27 and 144 is more than -200, and -13 is less than 6

Questions 13+(-6)=7 Explanation: Imagine the -6 as a debt,so that means you have a negative balance.However,you received $13 and paid the $6 Debt,you have $7 Left. -21+32=11 Refer to the above explanation but replace the values 6 and 7 with 21 and 32. 35+(-8)=27 Explanation:Refer to above explanation but replace values 21 and 32 with 8 and 35. 27+(-12)=15 Explanation:Refer to above explanation but replaces value 8 and 35 with 12 and 27. -37+22=-15 Explanation:Imagine your debt to be more than the money you receive,this means you lessen the debt but still owe money.So,you still owe $15 -46+18=-28 Refer to above explanation but replace values 37 with 46 and 22 with 18. -110+(-10)=-110 Explanation:Imagine you already owe $100 but you needed 10 more,you borrow that $10 and so you know owe $110. (-20)+(-5)=(-20)-5=-25 Explanation:Refer to above explanation but change value from 100 to 25 and 10 to 5.

Question C Group Members: Hong Jie, Wei Le, Hansen Question C isn't done, so we will continue it. (a) and (b) are all right. (c) -7-(-6)-5 = -7+6-5 = -6 (d) 4-(-9)-5 = 4+9-5 = 8

c) (-12)power of 2 is less than -200, not more than -200

We are doing Question A

DeleteB use number line to support your explanation pls.

Deletegroup members:kit hint,zen,royston

ReplyDeleteour group is doing question: example 1 (the one in blue)

we checked and feel that all the answers are correct except question E is wrong we all feel that the answer should be -15 instead of 15

Phaps show your group working pls

DeleteFor the third piece of work, example 2 part D the question is 4-(-9)-5

ReplyDeletethe working is since there are two negatives it means that 4 is suppose to be added to 9 therefore the answer for 4-(-9) is 13 then minus 5 as stated in the operation finally the answer is 8.

B - use math notation instead of El paragraph.

DeleteIs this individual work as I did not see any group members' names?

ReplyDeleteLast question: The working for this question is correct

B - how do you know they are correct - show your working too pls.

DeleteGroup members: Shaun Ho, Silas, Damien (19-21)

ReplyDelete4)

A) -7+(-11)+10

= -18 + 10

= -8

B) -10 + 17 + (-21)

= 7 + (-21)

= -14

C) [-9+(-15)]+[-20+30]

= -24 + [-20+30]

= -24 + 10

= -14

D) [30+(-45)] + [-15+(-10)]

= -15 + [-15+(-10)]

= -15 + (-25)

= -40

All 4 answers are correct

DeleteA - excellent work.

DeleteQuestion C

ReplyDeleteGroup Members: Hong Jie, Wei Le, Hansen

Question C isn't done, so we will continue it.

(a) and (b) are all right.

(c) -7-(-6)-5

= -7+6-5

= -6

(d) 4-(-9)-5

= 4+9-5

= 8

A - well done

DeleteGroup members: Hsu Hwee, Rayna and Audrey.

ReplyDeleteTier A

1. -7+(-11)+10=-18+10

= -8 ( correct )

2. -10+17+(-21)

= 7 + (-21)

= -14

3. [-9+(-15)]+[-20+30]

= -24+10

=-14

4. [30+(-45)]+[-15+(-10)]=

-15+-25=-40

(all correct:)

A - clear, concise and precise.
