Today in class we worked in our yellow booklet page 43 and 44. These questions that im doing is in page 44 , F. questions 1-5.

1. The temperature starts at -25 ○C, drops 13 ○C, rises 3 ○C and rises 8 ○C.

Question #1 we did it in class, heres how we did it :

-25, -13, +3, +8

First you have to group the positives and the negatives together. Then we put (-25)+(-13)+(+3)+(+8)=? . Then we added the positive and the negative numbers seperatly. So (-25)+(-13)=-38 (negative) . And (+3)+(+8)= +11 (positive). And added (+11)+(-38)= -27.


(-25)+(-13) = -38 and (+3)+(+8) = +11
(-38) + (+11)
equals= -27

(-25)+(-13)+(+3)+(+8) = -27
(-38) + (+11) = -27
-27 = -27


2. A person starts with $350, earns $122, spends $115, earns $183 and spends $29.

+350, +122, -115, +183, -29

For this question I kinda did it in a different way. First I grouped the positive numbers and the negative numbers, I also typed in positive and negative so you'll understand more. I also put +350, + 122, -115, +183, -29 so it would be easier. I put the positive and the negative orderly and add them. Then when i found out the answer for positive and negative, I added +655 and -86 and get +741.

positive.....(+350)+(+122)+(+183) = +655

negative....(-115)+(-29) = -86
(-86)+(+655) = +741
3. Gloria is 52 kg. She gains 5 kg, loses 7 kg, gains 9 kg and loses 14 kg.
For this question I did the same thing as the second question. I grouped the positive and negative numbers. And added again.
+52, +5, -7, +9, -14
positive.....(+52)+(+5)+(+9) = +66
negative....(-7)+(-14) = -21
(+66)+(-21) = +45
4. The temperature starts at 32 ○c, drops 8 ○, drops 3 ○, rises 9 ○ and drops 12 ○.
For this questions I did the same thing as
+32, -8, -3, +9, -12
positive....(+32)+(+9) = +41
negative...(-8)+(-3)+(-12) = -23
(+41)+(-23) = +14

5. A submarine starts at sea level, dives down 135 m, dives another 77 m, and rises 72 m.

-135, -77, +72

For this question I put (-135)+(-77) and added them and i got -212, then i added (-212)+(+72) and got -140.

(-135)+(-77)=-212

(-212)+(+72)= -140
