Comparing and Ordering Integers

This video tutorial covers the comparison and ordering of integers. It explains how to compare integers by examining their signs and using number lines. The tutorial provides examples of writing inequalities and interpreting them in real-world contexts. Additionally, it demonstrates how to order integers from least to greatest and greatest to least using number lines.

Which of the following statements is true about comparing integers?

• The magnitude of a number does not matter.

• Numbers with the same sign cannot be compared.

• Positive numbers are always greater than negative numbers.

• Negative numbers are always greater than positive numbers.

If you plot -3 and -2 on a number line, which one is greater?

• They are equal

• Cannot be determined

• 0

• -5

Justin has a score of -4 and Desiree has a score of -5. Which inequality correctly compares their scores?
