Adding Integers in Real-World Scenarios

The video tutorial covers solving integer word problems, including scenarios like debt repayment, submarine depth, platform height, and research vessel depth. Each problem is solved using integer addition and subtraction, emphasizing the importance of understanding positive and negative values in real-world contexts.

Mr. Stubbs owes his friend $25 and repays $14. What is the correct addition problem to represent this situation?

• 25 + 14

• 25 - 14

• -25 - 14

• -25 + 14

After repaying $14 of his debt, how much does Mr. Stubbs still owe?

• $-11

• $39

• $-39

• $11

A submarine is 30 feet below sea level and rises 13 feet. What is the correct addition problem to represent this situation?

• -30 - 13

• 30 + 13

• -30 + 13

• 30 - 13

Where is the submarine located after rising 13 feet from 30 feet below sea level?

• 17 feet below sea level

• 43 feet above sea level

• 17 feet above sea level

• 43 feet below sea level

Ms. Furlong is standing on a platform 23 feet above the pool water, walks down 7 feet, and then hikes back up 10 feet. What is the correct addition problem to represent this situation?

• 23 - 7 + 10

• 23 + 7 + 10

• 23 + (-7) - 10

• 23 + (-7) + 10

How high is Ms. Furlong above the pool water after walking down 7 feet and hiking back up 10 feet?

• 30 feet

• 20 feet

• 16 feet

• 26 feet

An underwater research vessel descends 1500 feet, rises 525 feet, and then descends again 350 feet. What is the correct addition problem to represent this situation?

• -1500 + 525 + (-350)

• -1500 - 525 + 350

• 1500 + 525 - 350

• 1500 - 525 - 350

Where is the underwater research vessel located after descending 1500 feet, rising 525 feet, and descending again 350 feet?

• 825 feet below sea level

• 975 feet below sea level

• 1825 feet below sea level

• 1325 feet below sea level

What is the first step in solving the problem involving the underwater research vessel's movements?

• Subtract 525 from 1500

• Subtract 350 from 1500

• Add 1500 and 525

• Add 1500 and 350
