The video tutorial covers identifying opposites and absolute values of rational numbers. It explains that the opposite of a negative rational number is positive and vice versa. Absolute value is described as the distance from zero on a number line, always non-negative. Examples include graphing stock value changes and calculating the absolute value of temperatures.

What are the two essential questions discussed in the video?

• How to multiply and divide rational numbers

• How to solve equations involving rational numbers

• How to identify the opposite and absolute value of a rational number

• How to add and subtract rational numbers
