Understanding Inequality Symbols

The video tutorial from Bru's Math Club teaches how to write inequalities with one variable. It covers four main types of inequalities: greater than, less than, greater than or equal to, and less than or equal to. The tutorial provides examples for each type, explaining how to convert verbal statements into mathematical inequalities using variables. Key terms are underlined to aid in writing the inequalities, and symbols are explained using simple analogies like the alligator mouth for greater than and less than signs.
