Comparing Positive and Negative Integers

In this video, Mr. J explains how to compare integers using a number line. He demonstrates four comparisons: -2 vs -3, -4 vs 0, 8 vs -10, and -13 vs -14. The key concept is that the number further to the right on a number line is greater. He also uses temperature as an analogy to help understand comparisons involving negative numbers.

Which integer is greater: -2 or -3?

• -2

• -3

• Both are equal

• Cannot be determined
