This video tutorial introduces the concept of absolute value, explaining it as the distance of a number from zero. The lesson covers the absolute value symbol, provides examples using a number line, and emphasizes that absolute values are always non-negative. The tutorial includes practice problems and a recap of key points, highlighting that opposite numbers have the same absolute value due to their equal distance from zero.

What symbol is used to denote absolute value?

• Two straight lines

• Square brackets
