IGCSE Mathematics Core C2.6.1 Represent and interpret inequalities, including on a number line Question Bank

• Represent and interpret inequalities, including on a number line. When representing and interpreting inequalities on a number line: • open circles should be used to represent strict inequalities (<, >) • closed circles should be used to represent inclusive inequalities (⩽, ⩾) e.g. – 3 ⩽ x < 1 –/uni202F3– /uni202F2– /uni202F101 x
