WebJul 22, 2024 · An interval notation is basically a way of describing inequalities on the number line. There are rules of expressing an interval notation to the number line: a closed interval is denoted with a shaded circle, and an open integral is denoted with an unfilled circle. WebExample: 4 < 6. 4 ÷ (-2) < 6 ÷ (-2) -2 < -3 <- See -3 is not greater than -2. RULE. If you multiply or divide by a negative number, flip the inequality symbol around to make the sentence true. Remember. Again, when we divided by a positive number, we still got a true statement. But, when we divided by a negative number, we got a false statement.
