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

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

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

(separately and you didn't make one of the *I* capital. But every thing else was fine
