Valuate an Absolute Value Expression

The video tutorial explains how to evaluate absolute values in a math test question. It begins by defining absolute value as the distance a number is from zero, which is always positive. The tutorial then demonstrates calculating the absolute values of 4 and -7, resulting in positive 4 and 7, respectively. Finally, it adds these values to solve the expression, yielding a result of 11.
