The symbol is ∈, not e. The statement in your title means “x in r”. It is always helpful to use the 'options' tab and begin a solution with 'a few steps', then increase the number of solution steps when the additional steps are helpful rather than overwhelming and/or confusing. For example, 1e6 would stand for 1 × 10 6, or 1 million. For short, you can say x is in r. Symbols save time and space when writing. When 2x = 4, then x = 2 = equals sign: Often used for denoting other types of similarity, for example, matrix similarity or similarity of geometric shapes. 5 = 2+3 5 is equal to 2+3: A set is a collection of things, usually numbers.
Common symbols used in set theory. Symbols save time and space when writing. A set is a collection of things, usually numbers. When 2x = 4, then x = 2 = equals sign: So basically, x ∈ r means is an element of r. We can list each element (or member) of a set inside curly brackets like this: Web xer or in maths means that is a real number belonging to a real set of numbers (r). So writing x∈r means x is an element of r (where r written in blackboard bold means the set of real numbers). Denotes the asymptotic equivalence of two functions or sequences. Equal by definition := equal by definition: The symbol is ∈, not e.
