In the given problem, apply your knowledge in algebra and basic mathematics specially in simplifying integer.
1. A loss of 20 and a gain of 15.
→ -20 + 15
2. A gain of 15, then a loss of twenty.
→ 15 - 20
3. A gain of 20 and a gain of 35.
→ 20 + 35
4. A loss of 19 and another loss of 30.
→ (-19) + (-30)
5. A raise of 15° and 10° fall in temperature
→ 15 + (-10)
6. An altitude of 30,000 feet and another height of 15,000 feet
→ 30 000 + 15 000
7. A loss of 15,000 feet and another loss of 12,000 feet.
→ (-15 000) + (-12 000)
8. A depth of 60 feet and a resting stop at 15 feet below the surface of the water.
→ (-60) + 15
9. A depth of 15 feet and then another descent of 20 feet below the surface of the water.
→ (-15) - 20
10. The hikers climbed to 1500 feet and then hiked another 1000 feet.
→ 1500 + 1000
