Just spell out the relationship. Don't be surprised if your book sometimes … Either spell out the "if-then" relation, or approximate the arrow using two "equals" signs, to differentiate "if-then" from "greater than or equal to". �jY��~��.ȈU脌m ��6�tL�� 9U)&F.

Oddly, though logic was studied before algebra was invented, the notation for logical statements (and the sets in whose context those statements are sometimes made) is less standardized than is the notation for algebra. Curly braces are commonly used to denote sets, so you can use curly braces with nothing between to denote the empty set. was always (modal operator), White square with rightwards tick, will always be (modal operator).
