Let’s solve each problem one by one, step by step.
---
Problem 1:
Monday temperature = -2°C
Tuesday: dropped by 5°C → so we subtract 5 from -2
→ -2 - 5 = -7°C (Tuesday)
Wednesday: rose by 3°C → add 3 to Tuesday’s temp
→ -7 + 3 = -4°C (Wednesday)
✔ Tuesday: -7°C
✔ Wednesday: -4°C

Problem 2:
Max’s scores: 35, -5, -2, 20, -10, 8
Add them up:
Start with 35
35 - 5 = 30
30 - 2 = 28
28 + 20 = 48
48 - 10 = 38
38 + 8 = 46
✔ Total marks = 46

Problem 3:
Sam deposits $1600 → that’s +1600
Then withdraws $1519 → that’s -1519
Balance = 1600 - 1519 = 81
✔ Balance = $81
---
Problem 4:
Plane is at +7500 m (above sea level)
Submarine is at -1600 m (below sea level)
Vertical distance = difference between them
= 7500 - (-1600) = 7500 + 1600 = 9100 m
✔ Vertical distance = 9100 meters

Problem 5:
Eliana goes 15 miles east from A to B → let’s call east positive
So B is at +15 miles from A
Then she moves 25 miles west → west is negative
So from B, she goes -25 miles
Final position from A = 15 + (-25) = -10 miles
That means 10 miles west of point A
✔ Final position = 10 miles west of point A
---
Final Answer:
1) Tuesday: -7°C, Wednesday: -4°C
2) 46
3) $81
4) 9100 m
5) 10 miles west of point A
