If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y.A symbol for the empty set. Common notations for the empty set include "{ }", "", and "∅".The latter two symbols were introduced by the Bourbaki group (specifically André Weil) in 1939, inspired by the letter Ø in the Danish and Norwegian alphabets. In the past, "0" was occasionally used as a symbol for the empty set, but this is now considered to be an …Type of Number. It is also normal to show what type of number x is, like this: The means "a member of" (or simply "in") The is the special symbol for Real Numbers. So it says: "the set of all x's that are a member of the Real Numbers, such that x is greater than or equal to 3" In other words "all Real Numbers from 3 upwards" The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. You may also come across other related symbols, although these are less common: ≠ means not equal. For example, 2 + 2 ≠ 5 - 2.Introduction.
