Understanding Positive and Negative Values

The video tutorial covers lesson 13 on ordering numbers in real-world scenarios. It includes examples and exercises on understanding transactions, temperatures, bank statements, water levels, and barometric pressure using rational numbers. The tutorial also explains the concept of absolute value and its application in real-world problems, such as comparing lengths of rope and understanding credit card debt.

What is the main difference between a credit and a charge in a bank account?

• Credit is a positive change, while charge is a negative change.

• Credit is a negative change, while charge is a positive change.

• Both are negative changes.

• Both are positive changes.

How should temperatures be ordered from least to greatest?

• Negative numbers first, then zero, then positive numbers.

• Zero first, then positive numbers, then negative numbers.

• Positive numbers first, then zero, then negative numbers.

• Positive numbers first, then negative numbers, then zero.

• Fraction

• Zero

• Negative

How much longer is the rope below the water compared to above in the fishing vessel example?

• 10 feet

• 15 feet

• 20 feet

• 23 feet

What is the absolute value of 23 feet above sea level?

• 46

• 0

• $15,000 is a larger rational number.

• $10,000 is a smaller rational number.

• $15,000 is a smaller rational number.

• $10,000 is a larger rational number.
