Understanding Opposites and Absolute Values

The video tutorial covers integers, absolute values, and opposites. Integers are defined as positive or negative whole numbers, excluding fractions, decimals, and percents unless they represent whole numbers. Absolute value is explained as the distance from zero, always positive, and represented by two bars. Opposites are numbers equidistant from zero but on opposite sides, such as 3 and -3.
