What is this symbol in mathematics.
1 Answer. Sorted by: 6. This symbol has no "modern equivalent," to my understanding, because it is still in use today. x ↦ y x ↦ y means, for an implied function f f, that f f maps x x to y y, i.e. f(x) = y f ( x) = y. You might have each side of the arrow written in a general form, such as x ↦ x2 x ↦ x 2 denoting f(x) = x2 f ( x) = x 2 ...

Writing means that the elements of the set A are the numbers 1, 2, 3 and 4. Sets of elements of A, for example , are subsets of A . Sets can themselves be elements. For example, consider the set . The elements of B are not 1, 2, 3, and 4. Rather, there are only three elements of B, namely the numbers 1 and 2, and the set .Math is all about numbers, symbols, and formulas. Math symbols are used for different purposes from one mathematical field to another. Using math symbols to represent information makes it easier to understand expressions.

Symbols and words. It is important to use words and symbols appropriately. Part of being able to write mathematics well is knowing when to use symbols and knowing when to use words. Don’t use mathematical symbols when you really mean something else. A common mistake is to misuse the \=" symbol. For instance: 32x 2(3x)= 1=(3x)2 2(3x)+1=0 =Proper subset definition. A proper subset of a set A A is a subset of A A that is not equal to A A. In other words, if B B is a proper subset of A A, then all elements of B B are in A A but A A contains at least one element that is not in B B. For example, if A = {1, 3, 5} A = { 1, 3, 5 } then B = {1, 5} B = { 1, 5 } is a proper subset of A A.
